A2 Generally 30% TT as the prepayment, 70% TT before delivery. If need, 100% Irrevocable Letter of Credit or negotiation.
Q3 Which country are our products exported to?
A3 Apart from entire Chinese market, the US, Russia, Japan, Korea, Australia and some Southeast Asian Nations.
- Q:How aluminium oxide becomes a entity from the the form of powder (such as a ball, a stone, or a refractory brick)?
- Just like the process of making steamed bun from flour. Ball milling ---in the auxiliary material to make the slurry --- suppress the body --- high temperature calcination
- Q:What are the sizes and sizes of clay bricks?
- At present, with the minimum size of the maximum size of the market, for the maximum size of the clay brick, there are 600*250*200mm, 180*115*90mm, 300*300*55mm, and the minimum sizes 150*150*150mm, 235*115*55mm and so on, the construction industry the most basic materials for clay brick, must use in daily life is very broad.
- Q:What is the heating temperature in the test method of thermal shock resistance of refractory bricks
- 1, quenching (air cooling or water cooling), after the completion of the specified number of times. 2, maintain 20min, introduce the following types briefly. 3, repeated testing and record the times of the material produces macro cracks. The thermal shock resistance is shown by the times of thermal cycle of damaging half of the heated end face, quenching(air cooling or water cooling ) there are many expressions and testing methods of the thermal shock resistance, and then dry. Put the heating end surface of standard size brick((200~230mm) X (100~150 m K (50~100mm) claw)into the preheated to 1100 DEG C 50mm in furnace, quenching (air or water), then quenching in room temperature water for 3min, measured the maximum temperature of sample surface produces cracks. After the temperature of the material rises to a predetermined temperature, the ratio of residual anti-bending strength and anti-bending strength at room temperature before heat shock, after the material rises to various temperatures, measure its strength retention rate.
- Q:How to calculate the pressure of hydraulic machine pressures refractory brick?
- If it is a plunger type cylinder, the pressure of a cylinder is the cross-sectional area of the piston multiplied by the pressure of the hydraulic system; if it is piston cylinder, that is the inner diameter of the hydraulic cylinder multiplied by the pressure of the hydraulic system. Adopt cm as diameter's unit, a unit of pressure is kilogram force per square centimeter, the calculated result is kilogram which divided by one thousand is ton.
- Q:What is the clay used to make the refractory brick?
- Lining brick of teeming ladle; refractory clay used in building materials industry to produce high alumina bricks for cement kilns and glass furnaces, as well as anti sliding, high alumina lining bricks and high alumina refractory clay. The hard clay in refractory clay is used for making blast furnace refractory material, which is used in agriculture as a fertilizer promoting agent and, and electron. High alumina clay is also used in the oil well, generally does not disperse in water. In metallurgy, accounts for 2/3 of abrasive products, and so on. Hard clay and semi hard clay can be used to manufacture daily-use ceramics. High alumina clay after calcination, which has high temperature resistance! Refractory clay refers to the degree of fire resistance is greater than 1580, the hardness and proportion is relatively big, the refractoriness is good. They except has relatively high refractoriness. Such as aluminum sulfate, its dosage accounts about 70% of all the refractory materials;
- Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
- But it depends on materials; for example, if clay brick is pink, it calls underburnt temperature is 700 degrees -900 degrees, paste red is called overdo temperature 1350 degrees -1390 degree, if the color turns heavier, it will be deformation. there are many reasons for refractory bricks sintering
- Q:Where the refractory bricks rider bricks that are used for building arch and vault should be put?
- Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.
- Q:What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
- except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
- Q:How to distinguish between sintered clay brick and sintered coal gangue brick
- Coal gangue is an industrial waste produced during coal mining. Using coal gangue as raw material for the production of new wall materials, both to protect the ecological environment, but also save the land, save energy, it meets the development policy of wall materials industry in China, is a new wall material attaches great importance to and vigorously support the development of the.
