Q:Is the ball mill used in production of refractories?: It depends on what refractory you produce.

Q:What kind of flexible fireproof material is really good?: Flexible waterproof materials mostly are asphalt, linoleum and other organic material, which is also called linoleum coiled material waterproof layer. it uses the linoleum, glass cloth fabric as tire layer coil, using all kinds of cementing material phase of asphalt and so on. Make coil bind on roof structure plate leveling layer to form waterproof layer. Flexible waterproof material has high tensile strength, big elongation and light quality, which is convenient to construct. But it has relatively strict operation technology can resistant penetration and aging resistance than rigid materials, aging. Its life is short. Refers to a kind of waterproof material form relative to the rigid waterproofing materials such as waterproof mortar and waterproof concrete. In the form of its and grassroots attached two categories, it includs waterproof coating and waterproofing materials. According to different paste position of waterproof material, it can be divided into outside waterproof waterproof (outsourcing) and inside waterproof (insourcing waterproof) two kinds. Waterproof coil material must be stuck in the grass-roots that have enough stiffness of the. Before pasting, you should apply leveling layer and waterproof layer should be added protective layer of the outside, and need to make the rotation of the flexible material, the processing of subsequent and head closing, in order to ensure the continuity of the waterproof layer and sealing. In addition, there are all kinds of waterproof material and moistureproof coating material.

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.

Q:How to divided the grade of external wall thermal insulation materials?: Synthesized the three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. Please contact Qingdao Shanfang Instrument Co., LTD for details, they specialized in the external wall thermal insulation materials fire?rating test

Q:I know which material is the fire resistance rolling shutter door: the materials of fire resistance rolling shutter door are: the inner of fire resistance rolling shutter door is generally filled with aluminum silicate fiber cotton. fire resistance rolling shutter door is divided into AAA inorganic fireproof rolling shutter door and steel fire resistance rolling shutter door. the fireproof?performance of inorganic fireproof rolling shutter door is better, but steel fire resistance rolling shutter door has a certain wind load resistance, which can be installed outdoors.

Q:What are the refractory stocks?: The company produces energy saving, environmental protection type functional refractory materials and unshaped refractory materials. It is the main functional refractory material and unshaped refractory production enterprise in china. Company's products to new green high-quality refractory materials, energy saving and environmental protection as the leading iron and steel industry technological progress and improve the level of technology and equipment to adapt to meet the "development policy" refractories industry to develop industry, has a strong competitive advantage in the market. The main domestic refractory products company can only use part of the products of refractory materials production of iron and steel industry, iron and steel industry production and Pu resistant can be used in the vast majority of refractory products, iron and steel industry with the most complete refractory products. Therefore, the future development of the company is closely related to the prosperity of the iron and steel industry. More than more than 2000 enterprises in refractory industry, the company is the largest supplier of refractory materials in China, and the market share is less than 2%. Iron and steel group integration will inevitably lead to the overall contract cost control, supplier refractory decreases by seventy or eighty to two or three. The company's overall contract accounted for 37% (Montreal 68%), the overall contract increase will enhance the market share and profitability. China's urbanization, industrialization and investment in the 4 trillion infrastructure will stimulate sustained and rapid growth of China's steel demand. Therefore, in the long run, the prospects for the development of refractories for iron and steel are broad.

Q:What do refractory materials include?: It is so difficult.

Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !: First, the materials are the same. But the thickness of grade A and grade B fire doors is different juding from their appearances. Grade A :50. Grade B:45. Added question: Do you refer to steel fire door?

Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??: which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.

Q:I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?: Metallurgical industry downturn. There is fierce competition in the refractory industry.
