Product Description

CNBM fire brick is an alumina-silicate refractory material in which the Al2O3 content is more than 55%, and is calcined from a high-content alumina raw material such as a silicone raw material or a bauxite. High heat resistance and high temperature resistance at 1770 ° C and above. Has good slag resistance, mainly used in the masonry of steelmaking electric furnace, glass furnace, cement rotary furnace and so on.

Q:Application characteristics of high alumina brick: Thermal shock stability. In high alumina brick products, the stress concentration is due to differential expansion when the temperature of refractory brick changes. Therefore, the high aluminum brick products than clay brick products thermal shock stability is poor, general water temperature only 3 - 5 times.

Q:Difference between low creep high alumina brick and ordinary high alumina brick: The question is good, these two belong to the high aluminum brick products, when many manufacturers buy, I do not know how to distinguish.

Q:What does refractory consist of?: According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.

Q:What's the difference between a well type annealing furnace and a box type annealing furnace?: Box annealing furnace application: mainly used for quenching, normalizing, annealing and other conventional heat treatment equipment for steel parts. Features: 1, electric loading, high productivity, heat treatment is especially suitable for small and medium-sized parts, such as 30%, uniform temperature, intelligent digital display meter PID (pictured) automatic temperature control, high precision; 2, electric discharge loading convenient, as good; 3, door and seal the oven body is sealed automatically, without manual seal; 4, equipped with electric interlock protection device, and can prevent the fault accident due to the error. Bell type annealing furnace four bell type annealing furnace bell type annealing furnace is mainly used for annealing sheet metal in natural atmosphere and normalizing treatment of steel parts. 1, special steel, precision alloy large all fiber trolley type resistance furnace, strip, wire bright annealing. 2 、 annealing of special steel casting and forging. 3. Annealing of silicon steel sheet. 4, metal and non metal powder sintering pieces etc..

Q:In 2016, a few of the traditional refractory materials will be able to survive: From the year 2015 to the year 16 the end of the year, refractories industry presents two kinds of situations: one is a small business, a single product variety and equipment, to meet the demands of both environmental protection and the downstream market, such enterprises are generally in the Qing state inventory;

Q:What are the categories of bricks?: Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels.

Q:What are the grades of high alumina bricks?: According to the size of high aluminum brick is divided into: standard brick, special-shaped brick.

Q:Is glass wool inorganic thermal insulation material?: Yes, glass wool belongs to one kind of glass fiber. It is a kind of man-made inorganic fiber. Therefore, in the field of thermal insulation materials classified as inorganic insulation materials.

Q:What is the price of the latest thermal insulation material?: There are many kinds of insulation materials, and the price will fluctuate with the market. Small quantities of inquiry or procurement, then go directly to the local thermal insulation market, a wide variety of prices are basically the market price.

Q:What should be used as binder for making high alumina bricks?: In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
