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 is the importance of silicon powder in refractory processing?
- it depends on the type of refractory material, in addition to lS friends talked about, in the amorphous mobility\ strength should also have an impact
- Q: What is the role of adding chromium oxide green in unshaped refractory materials
- Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
- Q: Who knows the setting requirements of roofing fire barrier zone?
- First, the the minimum of fire barrier width is greater than 30cm, and the thickness should be same to the thickness of the insulation materials. Fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. Fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. Second, Fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. The thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Third, When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. Flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. I hope you can be satisfied
- Q: Is refractory material harmful to human body?
- The risk of mineral wool and glass fiber have cancer!
- Q: How many kinds of fireproof materials are there in the market?
- Inorganic insulation materials basically can achieve the goal, such as glass wool, rock wool, and foam glass. The phenolic foam in the organic foam materials is special. Phenolic foam is not only good at insulation, but also good at compounding with steel and other materials to achieve A-level performance, and the A-level insulation materials are: rock(ore) wool, foam glass and inorganic thermal insulation mortar. Insulation materials with B1 combustibility mainly are: Phenolics, polystyrene granules, etc. The insulation materials of fire barrier zone can use such A-level materials as rock (ore) wool, foam glass, and inorganic thermal insulation mortar, etc.
- Q: What are the materials for refractory materials? What are their names?
- Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions.
- Q: what's the fireproof levels of fireproof and thermal inuslation matertial?
- at present,thermal insulation and fireproofing materials on the market include inorganic thermal insulation bead board(Shanghai Benniao construction and energy saving decoration materials company) rock wool (Hebei Shenzhou glass wool products co., LTD.) foamed glass ceramic (Nanjing Institute of Building Research) or sogou search.
- Q: What are fireproofing materials?
- Plants often use the fireproof sealing material with steel structures without much modification. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. . Coatings are usually those with fine powder, high density and good sealing. Hardeners mainly depends on specific requirements. .
- Q: What is refractory aggregate?
- Refractory aggregate is fire-resistant product improved with low temperature binder, chemical?compound and normal temperature strength.
- Q: Where do China and foreign countries do more refractory materials?
- Zhengzhou real gold refractory materials Co., Ltd. specializing in the production of non-ferrous industries, glass kilns, cement kilns with a variety of refractory materials, factory direct sales, reasonable prices.
