Q:What is the refractory brick of the electric furnace?
there is no problem if it can be dismantled. And refractory brick material of every place is not the same, life is not the same. Buy some for backup , and change it once it is broken, there is no standard, the lining can be hit, as long as the induction coil can be fixed
Q:What kind of refractory brick is suitable for 1400 degrees shuttle kiln?
Corundum mullite
Q:Why can earth make bricks?
Brick is a common masonry material. Brick and tile production and use in China has a long history, "Qin Zhuanhan tile". The raw material for brick making is easy to obtain, the production process is simple, the price is low, the volume of urine is in the combination, and the clay brick also has the advantages of fire protection, heat insulation, sound insulation, moisture absorption, etc..
Q:What is light brick and what are the characteristics of light brick?
The design uses the light brick to use the solid clay brick, because the block is big, and the sound insulation effect is good, shape up through the high pressure, reducing the labor intensity! Strength of the products use high quality tabular corundum and practical mullite as aggregate, the use of air conditioning: The use of lightweight brick can increase the usable area, indoor temperature decreases by 2-3 DEG C compared to the use of solid clay brick, reduce the frame section, high alumina high strength bead brick, shorten the construction period, the economical efficiency, with sillimanite as matrix composite lightweight brick generally refers to foam brick, high temperature sintering, will not increase the weight of the floor, low iron mullite, good thermal insulation effect: Can reduce the cost of foundation. The production materials for ordinary light heat insulating refractory brick including clay, diatomite insulation refractory brick. The characteristics of light brick: 1, construction is convenient and simple. 2: The lightweight brick has good workability, saving reinforced concrete can significantly save the comprehensive cost for building, comprehensive cost can be reduced by more than 5%, at the same time, as aerated concrete has thermal insulation, in hot summer, light weight, lower power consumption, high aluminum light insulating refractory brick, improve construction efficiency, normal indoor partition is built by this kind of brick, add special additives and a small amount of rare earth oxides refining.
Q:Why are clay bricks used when buildings are below zero? Frost heaving, water absorption, or something?
The following buildings plus or minus zero use of clay bricks is used because the clay brick has good water absorption, can make the capillary water in the soil up to the clay brick, clay brick is absorbed, so as to prevent the capillary water rising effect
Q:Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
Now is the best thermal insulation hollow powder briquette, because it is hollow, blocking the heat transfer, plus foam insulation on the outside, good insulation effect,
Q:what kind of refractory brick is suitable for 1300 degrees converter?
The furnace cap tapping shaft part should use MgO-C brick with high slag resistance and thermal shock resistance, the steel side can be slightly thin, bottom carbon content may be appropriate less.
Q:What are the differences between fired brick and clay brick?
Clay brick is a kind of sintered brick, which is made of clay as raw material. Clay brick, ceramic tile and rock sheet brick also belong to sintered brick, so the range of sintered brick is wide.
Q:What's the price of clay bricks?
Clay brick in the fast price of 2.4 yuan or so, the price of 650-800 yuan per ton. Mainly depends on the amount of aluminum. Clay brick consists of heavy clay brick and light clay brick.
Q:The boiler is divided into several categories according to the structure, what characteristics does each have?
package boiler and assemble boiler are divided into vertical boiler and horizontal boiler. Vertical boiler. Assembled boiler adapts to boiler more than 6 tons, the package adapts to boiler less than 10 tons.
