CSP slab CCM mold protect slag
Product description
Be known as metallurgical technology "high-tech" thin slab continuous casting in the past two years developing fast in China, and with the pearl river steel, handan steel company baotou steel companies and companies such as introducing CSP technology, now and a number of handan has gone into production. Corresponding to bring thickness thin, drawing speed high thin slab continuous casting mould manufacture of protective slag production problem, 2003 with the joint work BeiKeDa developed, and obtained the breakthrough, low carbon steel, middle-carbon steel and experimental results show that the protective slag reached the country slag protection quality level, to prevent leakage steel and binding in slab surface quality better than import slag, be expert evaluation for domestic alternative product.

- Q: what's the seal of fireproofing material?
- Folded organic putty takes organic material as bond,it has certain flexibility or plasticity while using, and it's products are thick liquid or cement shaped object. Folded WXY-II is powered?solid that takes inorganic materials as main components, it has certain workability while used with admixture. Folded fire retardant bag is the packaged object made by fireproofing material, and it's suitable for fireproofing seal of larger openings or fire separation of cable?bridge(fire retardant bag also refers to fireproof bag) Folded fire retardant module is the solid made by fireproofing material with certain shape and size, and it is easy for cutting and drilling, suitable for fireproofing seal of opening and cable?bridge. Folded seal board is made by fireproofing material, it's easy for cutting and drilling, suitable for fireproofing seal of large opening. Folded foam seal is a kind of fireproofing material that can automatically expand and foam and sealed by opening after injecting the foam into opening. Folded sealing strip is a product or flexibility coiled material mede by fireproofing material with certain geometry shape. Folded sealing gum is a kind of liquid fireproofing material that has a function of fireproofing and sealing. Folded fire retardant bag is soft and windable tape-shaped product made by fireproofing material, it is winded on the external surface of plastic pipe and fixed with steel belt or other proper methods, it's the expansion, squeezing and softening pipe after contacting with fire, opening left by burning or soften of seal plastic pipe. Folded fire retardant ring is the product made by fireproofing material and metal shell, it's covered on the external surface of the plastic pipe, expanding and sealing after contacing with open fire, the opening left by burning and soften of plastic pipe when it passes through the opening of wall and floor.
- Q: What are included in roof thermal insulation fireproofing material?
- Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire?retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
- Q: How long is the duration of fire resistance that fireproof window of level B can endure?
- The duration of fire resistance: fireproof window of level A shall not be less than 1.5h, while level B shall not be less than 1.0h. The frame of both fire proof windows A and B are made of steel, and the glass, not less than 26mm, is composite insulation fireproof glass. Monolithic fireproof glass window is neither B fire proof window nor A fire proof window, but non insulated fire proof window.
- Q: What refractories are resistant to fluorine gas?
- It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica?brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
- Q: What are the models of bauxite with high alumina?
- China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.
- Q: Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
- Add some hair and slags, or it will crack before calcination.
- Q: Who knows about the grade C fireproof door materials?
- I am happy to answer your questions. Wood or steel materials are usually used. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively. I hope my answer can help you.
- Q: Does anyone know what is the use of waste refractory materials?
- 1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.
- Q: What refractory materials are used in power plant
- And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
