High Temperature Castable Refractory Cement
Product Description
Refractoriness of not less than 1580 °C cement. According to the composition of different can be divided into low calcium aluminate refractory cement, calcium aluminate cement, calcium aluminate cement and dolomite refractory cement. It can be used for various refractory cement cement refractory aggregate (such as corundum, Calcined Bauxite,etc.) made of refractory mortar or concrete, used in cement rotary kiln and other industrial furnace lining.
Specifications
Refractory cement lining baking, must pay attention to the following matters:
1) at room temperature 350 degrees, most likely caused by local spalling, special attention should be paid to slow baked. As in the 350 degree heat preservation is still a lot of steam coming out, still should slow heating rate.
2) in poor ventilation, water is not easy to discharge conditions, to extend the preservation time.
3) when using heavy oil for baking, to prevent oil spray on the lining surface, to prevent local burst.
4) when using firewood baked, direct contact with the flame is often caused by local heating too fast, should be protected.
5) on refractory cement pouring, at least by 3D after baking.
6) for refractory cement lining cooling slowly, avoid the forced ventilation.

- Q: how to use boiler fireclay
- Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.
- Q: About the market issues of thermal insulation material and refractory material.
- After all, most people have the characteristics of being accustomed with something and it will not change easily ; second, the South has few material manufacturer, but in the Northeast, there are thermal insulating and refractory material manufacturers, which is in shortage, however, but irt is in the minority, and in many areas it is not suitable for exploitation of mineral (due to heavy industry and agriculture land and other reasons). I hope that my answer will help you. first, in the Northeast, the refractory material is not very rich, but the thermal insulating and refractory material demand is very large; third; fourth, which material is used more relived, after all, we should take the transportation costs into account, and it will depend on the kilns construction engineers being willing to use which kind of material, and the thermal insulation material procurement in northeastern region is mostly from the north.
- Q: What are the refractory materials above 1000℃
- It is a piece of cake to meet your requirement, anyway you can try unshaped castables like corundum and other refractory materials used in steelmaking which are above 1500℃ basically .
- Q: How long is the fire resistance time of the AAAfire resistance rolling shutter door?
- How long is the fire resistance time of the AAA fire resistance rolling shutter door?
- Q: Which kind of external wall fire barrier zone material is better?
- The following types are: rock wool, aerated concrete, phenolic aldehyde and foam cement rock wool fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass?fiber mesh and decorative mortar finishing layer or coating. Good air permeability
- Q: What is the acceptance standard of refractory?
- Feeler gauge is used to check the thickness of the refractory brickwork joint. The top of the gauge can not be sharpened. Feeler gauge is of the width of 15mm, length of 100mm and thickness of 1, 1.5, 2 or 3mm. The thickness is eligible when the depth which the feeler gauge is inserted in is less than or equal to 20mm. Ten places should be inspected per 5m2 of masonry surfaces. It is qualified when the condition in which thickness of the brickwork joint is 50% larger than a predetermined depth is not less than five times and it is excellent when the condition is no more than two times.
- Q: The performance of refractory material
- The mechanical properties of refractory material include withstand voltage strength. The structure properties of the refractory materials include porosity, bulk density, such as thermal emission rate. The physical properties of the refractory materials include temperature conductivity structure performance, wear resistance, hiphotos, electrical conductivity, creep, the hydration resistance, adhesive strength.
- Q: Does anyone know fire-proof material of fireproof wooden door?
- Because the timber of fireproof wooden door has gone through fire retardant treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method. Spraying method and soaking method are generally used for timber surfaces which are no longer going through planing process, and thin plate fire retardant treatment, whose thickness is less than 10mm . Vacuum method and vacuum-pressure method have excellent flame retardant efficiency, but their equipment are expensive. Fireproof wooden door refers to the door whose fire endurance of door frames, skeleton of the door leaf, door panels made of timber or timber work reaches the provisions of "GB50045-95 design of tall buildings for fire protection".
- Q: What are the additives and recipes of refractory?
- You can try FDN.
- Q: What are the uses of refractory materials of glass furnace?
- What are the uses of refractory materials of glass furnace? The refractory materials of glass furnace have a good corrosion resistance to steel slag, but are poor in thermal shock resistance, and the deformation temperature of loading at high temperature is low. Magnesite chrome bricks which are made of chrome ore and magnesia In different proportions have a good thermal shock resistance. They are mainly used as crown bricks of basic open-hearth furnace. The refractory materials of glass furnace are mainly applied to open-hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting as well as some high-temperature thermal equipments, and they can be used for reaction tanks and liners of autoclave.
