Sliding Gates
High temperature sintering sliding gate
Using the raw materials of tabular alumina, zirconia-corundum, carbon and other high-grade additives, after sintering to obtain characteristics of oxidation resistance, scour strength, erosion resistance, thermal shock resistance, shape stable and long service life, made our products the preferred materials for the large and medium-sized steel ladle, refining ladle, series of alloy steel ladle, and tundish. Our high performance sintering sliding gates include alumina carbon , Al2O3-ZrO2-C, etc, can meet the needs of different steel grade.
Metal bonded unburned sliding gate
This kind of sliding gate importing special metallic additives, which generate the phase has excellent high temperature performance behavior in the process of using. The using effect on the large and medium-sized steel ladle and the tundish is good.
Metal bonded unburned sliding gate has the following characteristics:
Sliding gate do not have carbon, there will be no carbon oxidation cause massive sgraffito surface, which is more suitable for low-carbon steel, ultra-low carbon steel and the casting of Stainless steel. Magnesia bonded sliding gate is particularly well suited for high calcium treatment steel, killed steel, rimming steel, etc. For special steel there will be no groove at the sliding zone.
Good thermal shock stability and cracks in using is small, guarantee the security of casting steel.
The use of the product performance is stable and the production cycle is short.
- Q: A chemical problem with refractory materials
- In chemistry, there is never absolute
- Q: Can someone professionally introduce the classifications of refractories?
- Whatare the classifications of the refractory index levels? There are three categories of refractory index levels. Anyone familiar with the industry may already know that if you're new to the refractory and don't know much about it, the following information may be helpful to you. Refractory index level can be devided into three general categories of special refractories, advanced refractories and ordinary refractories. The first category, special refractories. Whose refractoriness is higher than 2000 ℃, spinel brick, pure oxide products, high purity directly bonded magnesia-chrome brick, cast products, non-oxide products belong to this grade. The second category, advanced refractories. Whose refractoriness is from 1770 to 2000 Celsius degrees, mullite bricks, high alumina brick, magnesia-alumina brick, ordinary magnesia products, olivine bricks, ordinary magnesia-chrome brick belong to this grade. The third category, ordinary refractories. Whose refractoriness is between 1580 and 1770 Celsius degrees, equivalent to Al2O315% ~ 45% refractory products in the binary system of SiO2-Al2O3. Kaolinite is the main mineral of raw materials.
- Q: What kind of material is good for cabinet fireproof board
- Cabinet fireproof plate can be classified into fiber cement fireproof board, metal fire proof board, mineral wool fireproof board, perlite fireproof board, all sorts of fire prevention board. Fiber cement fireproof board is a kind of ornament plate using siliceous or calcareous as main materials and combined with a certain proportion of fibre material; metal fireproof board is a kind of decorative plate made of aluminum plate, stainless steel plate, color steel plate and other metal materials as the main raw material and added by certain flame retardant materials. Mineral wool fireproof board is a decorative plate made of mineral wool and glass wool; perlite fireproof board is hollow fire proof plate made of low alkalinity cement as the main raw material, and supplemented by certain perlite with fireproof function as filling. Fiber cement fireproof board is a kind of new material increasingly gets popular with superior heat insulation, sound insulation performance, belonging to the A1 level fire materials 1, Suzhou total surplus purification A-grade fireproof rock wool colored steel rock wool board range of applications: Partition ceiling material: Rock wool reference price: On a square 58.00/2 meters, Huarui thermal insulation fireproof materials aluminum silicate refractory aluminium silicate A-grade fireproof heat insulation aluminium silicate plate temperature: 1000 core material: Reference price for aluminum silicate fiber cotton: $3500.00\ ton
- Q: Who knows what is the standard of insulation material whose fire proof is level A?
- Non combustible materials of level A: WW inorganic active wall thermal insulation material, Cement foaming thermal insulation board, Glazed hollow bead insulation mortar, rock wool board, Glass wool board, Foam ceramic.Non combustible materials of level A, endowed with low density, low thermal conductivity, higher bearing capacity, convenient construction , economy and durability, are widely used in heat pipe, heat equipment, other industrial pipeline equipment , thermal insulating materials on industrial buildings, and used as heat preservation, thermal insulation, sound absorption materials of industrial and civic buildings.Non combustible materials of level A are used more for refractory protection coating material of steel structure because of its good thermal stability.
- Q: Which brand of thermal insulating refractory is good?
- The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Guangdong ALISON nanometer aerogel is more expensive. The heat conductivity coefficient is 0.018. It can work under 1000℃
- Q: What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
- Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
- Q: How to prolong the furnace age of Induction furnace by using fireproof materials?
- magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
- Q: Fire resistance and evaluation of refractory for casting
- The products to be tested are broken and ground, adding organic binders (usually dextrin) that do not affect the refractoriness. Water is used to make standard sized test cones, as shown in figure 1-2-1. Test cone is positive, three edge cone, the bottom side length of 8.5mm, the top side length is 2mm.Test, the equivalent of high standard cone refractoriness of the 2 products to be high, No. 1 and No. 1 high temperature low standard cone of each one, and the 2 to be tested in accordance with regulations frustum cone plug made of high aluminum material, a cone prism and vertical 8 degrees. 1 degrees tilt angle. Then, the cone is heated in a high temperature furnace. When the test cone with a high temperature and bending down to the standard cone top contact cone, the high standard cone refractoriness refractoriness is running.
- Q: Does anyone knows which company produces the better refractory materials?
- 1, Xinjiang Seekon new material limited liability company: Xishan Street No. 382,Saybagh District 2, Refractory Material Co., Ltd. In Xuyan, Benxi: Near the Sihu Road, Benxi City 3,Benxi Beitai new refractory material factory sales office address: Benxi city Sihu District Liu Toro No. 16
- Q: What is the limit of fireproof rolling shutter?
- According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
