The distinction of firebrick and heat preservation brick

Firebrick has density big, intensity is high, wear-resisting, corrosion resistance can be good, hot coefficient of expansion is small, abrade efficiency is tall, noise is low, service life is long, do not touch contamination makings to wait for an advantage. It is the high grade and abrade medium that suits to fetters at all sorts of muller.

Build by laying bricks or stones of firebrick kiln furnace is built should build a project according to build by laying bricks or stones of furnace of GB 50211-2004 industry construction and check and accept a standard to carry out. This standard set include indeterminate form fireproof material, fiber of fireproof pottery and porcelain, blast furnace reachs his accessory equipment, jiao Lu reachs dry extinguish anxious device, steel-making furnace reachs relevant device, heating furnace, heat treatment furnace and annealing furnace, show converter of furnace of pyroelectricity of furnace of fast furnace, fusion of Ai Salu, circumgyrate, mine, horizontal, stationary finery and circumgyrate type finery, aluminous electrobath, electric stove of carbolic element to calcine and furnace of carbolic element roast, vitreous kiln furnace, rotary kiln, limekiln reachs his accessory equipment, channel kiln and roller path kiln, change furnace and splitting decomposition furnace, industrial boiler, wintry period construction, check and accept a data, drying-out, construction safety and environmental protection.

The model of standard — norms of firebrick:

The norms model of firebrick is the accident regulation that points to firebrick over all dimension, the model of firebrick is current model, abnormity model, general abnormity model, distinctive form type to wait according to over all dimension and use body cent, also can produce manufacturer and the circumstance that use unit knows each other well in both sides to leave measure of collective and custom-built firebrick according to firebrick. The measure of appearance of a few kinds of firebrick sexes that its middling uses sees next tables.

Brick of light qualitative heat preservation, main effect is heat preservation, reduce caloric prediction of a person's luck in a given year to improve thermal efficiency then. It is a kind of science, efficient energy-saving technology measure, make caloric sends out the measure that conducts speed to decelerate.

1, heat preservation function:

The coefficient of thermal conductivity of brick of light qualitative heat preservation is in commonly ℃ of 350±25 of 0.2-0.4(average temperature) W/m.k, and the coefficient of thermal conductivity of firebrick is in ℃ of 350±25 of 1.0(average temperature) W/m.k above, many the heat preservation performance that can reach the heat preservation function of heat preservation brick wants to compare firebrick from this is good.

2, fireproof degree:

Of brick of light qualitative heat preservation fireproof degree be in 1400 degrees commonly the following, and of firebrick fireproof degree in 1400 degrees of above.

3, density:

Brick of light qualitative heat preservation is light qualitative insulation material commonly, density is general the density of in 0.8-1.0g/cm3 firebrick is in basically 2.0g/cm3 above.

Brick of light qualitative heat preservation does not contact content of melt of blaze, high temperature and chemical gas directly commonly erode, firebrick reachs manage to change function to be able to use all sorts of eroding at enduring what the broil with direct blaze bakes content of melt of the high temperature in the furnace that reach kiln character according to different capable person.

In respect of scope of application, the application of firebrick is far the use frequency that is more than heat preservation brick. But, in last few years, as environmental protection the buildup of energy-saving consciousness reachs what high temperature heats up effect to use, the application with heat preservation wide also brick purchases limits in what kiln furnace build by laying bricks or stones builds in. Appeared especially bricks of all sorts of new-style light qualitative heat preservation: Brick of Mo Laishi heat preservation, tall aluminium gets together light brick, alumina is hollow ball brick.

Heat preservation brick is complex of material of a kind of use high polymer a kind of new-style building materials. Main effect is the heat preservation, material that reduces caloric prediction of a person's luck in a given year to improve thermal efficiency then. It is a kind of science, efficient energy-saving technology. And fireproof it is general component is two kinds, do not finalize the design namely fireproof material and finalize the design fireproof material. Adventitious fireproof material also cries pouring makings, be mix a kind by a variety of aggregate or collect makings or a variety of sticking and the mixture that the agent comprises is farinaceous a makings. Finalize the design fireproof material points to firebrick commonly, its appearance has standard regulation, when also can be being cut according to needing to build, machine temporarily.
