Specifications

We can supply Insulation firebrick, alumina hollow ball brick, acid resisting brick, refractory brick, high alumina brick.

Insulation firebrick Detailed Product Description :

 Insulation firebrick , the most competitive price,good quality,safty packing,prompt delivery time,and excellent after-sales services.

Lower ferric Oxide,lower porosity,higher refractoriness,higher density,higher CCS and exact tolerance.

 

 Insulation firebrick :

Using big vibrating table and adopting special castables, the company produces furnace large fireclay blocks with vibrate moulding technology. The physical and chemical properties and appearance of the blocks have exceeded the national standards. The resistant ability to molten glass of the products is better than that of fanditional casting process products and ramming products . the products are especially suitable to build the bottom of furnace, cooling and working end side wall of glass furnace.

Insulation firebrick Typical Application :

Lining of hot-surface of industrial furnaces as carbon furnace, cracking furnace, heating

furnace for oil refining, roller kiln, tunnel kiln.

 Back lining insulating layer of industrial furnace as glass tank kiln.

 Deoxidizing atmosphere furnace.

Q:What is the high temperature limit of refractory bricks and refractory soil?
According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.
Q:What refractory material does cupola lining use?
A class of inorganic nonmetallic materials with a refractoriness of not less than 1580 degrees. Refractoriness is defined as the temperature of a sample of a refractory cone sample that resists high temperature without loading and does not soften and melt down. But only in terms of fire resistance can not be fully described refractories, 1580 degrees of temperature is not absolute.
Q:What causes breakage of refractory bricks?
There are many factors that lead to the damage of refractory brick, can be divided into: the chemical loss (e.g. salt penetration, redox phenomenon), heat loss (burning, thermal shock), mechanical loss (kiln deformation, thrust, brick masonry quality etc.).
Q:What is the apparent porosity of high alumina brick?
In the production of high alumina bricks in addition to the entity, there are many different sizes and shapes of different pores, pores can be divided into three categories: one side closed the other side and the outside world is called open pores, closed in the product not communicated with the outside is called closed pores, penetrating through pores called the few products.
Q:How to reduce the harm caused by two times mullite in high alumina refractory material
Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.
Q:How does the physicochemical index change when the high alumina brick is used at high temperature?
If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.
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:What's the difference between a well type annealing furnace and a box type annealing furnace?
RT3 series trolley type resistance furnace is a national standard energy-saving cycle type operation furnace. It has super energy-saving structure, adopts fiber structure and saves electricity 30%. Exclusive production of composite high aluminum nails group, car anti-collision sealing brick, automatic sealing trolley and furnace door, integrated rail, without the basic installation, placed on the ground floor can be used. Mainly used for high chromium, high manganese steel castings, ductile iron, roller, steel ball, 45 steel, stainless steel quenching, annealing, aging, and various mechanical parts heat treatment. Features: 1, no noise, no environmental pollution. 2, small heat storage, less heat loss. 3, high temperature control accuracy, furnace temperature uniformity. 4, a high degree of automation, simple. 5, PID programming can be used to set, fully automatic operation. 6, good sealing, long life, safe and reliable. Widely used in chemical, petroleum, food, metallurgy, machinery, light industry, electricity, ships, paper, mining, medicine, central heating and other industrial sectors. With the development of social productive forces, its application in various industries is more and more widespread. Two, pitannealingfurnace (for example: flange heat treatment furnace) use: the furnace for metal parts, such as ring of equipment heat treatment at rated temperature: the furnace is composed of furnace body and a movable furnace cover and control system.
Q:What is the difference between metal compounds and metal solid solutions?
A series of intermetallic compounds occurring between transition metals in intermetallic compounds. The most important are L sigma sigma phase and ves phase, they are topologically close packed (TcP) phase, they consist of a small atomic radius of a dense layer, which is inlaid with a large atomic radius of atomic structure, this is a highly dense pile. In addition to atomic size factors, their formation is also influenced by the concentration of electrons.
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.
