Refractory for heating furnace

Posted by adela li on October 24th, 2017

With the large-scale and high efficiency of the rolling mill, the heating furnace put forward higher demand, its development trend is large, low consumption, pollution-free and operational automation, building materials and therefore divided into side-open and lift Two kinds. The door is generally made of clay brick, refractory castable or refractory plastic, high aluminum insulation brick or refractory fiber mats and other materials for lining. Side open the door can use a furnace service, lift door due to temperature fluctuations and mechanical impact and other factors, the service life of about la. Out of the riveting with refractory material with the side of the billet heating furnace.

In addition to water-cooled cast iron out of the trough, the general use of high alumina brick or masonry masonry, the service life of 3 to 6 months. Sintered mullite or fused mullite large brick masonry, high strength, good wear resistance, but the thermal shock resistance is poor, easy to crack, its life around 1a. The use of heat-resistant steel fiber staggered corundum refractory castable in the field into the overall steel trough, the service life of more than 2a.

Ceramic chute with a small push-type refractory furnace, from the corundum a silicon carbide slide rails composed of ceramic slide. In the length of the furnace with a refractory brick masonry two or four rows of the wall. In the base wall masonry high alumina silicon carbide brick, and then install the sliding rail brick and composed of ceramic slide. Billet in the slide on the move to achieve the upper and lower sides of the heating, with less energy, billet without black and so on. Ceramic chute to withstand high temperature, billet load, high temperature wear and corrosion of iron oxide slag and other effects, the use of more demanding conditions, the life of about 1a. The bottom of the water cooling 'adiabatic refractory materials, large and medium-sized push silver or walking beam furnace, the bottom of the water cooling pipe is a vertical, horizontal distribution and support the role of thick-walled water cooling pipe composition. The purpose of adiabatic is to reduce the heat from the cooling medium, reduce the billet black print and improve the quality of heating.

The adiabatic way is divided into special-shaped clay brick mosaic or horseshoe-shaped brick hanging, refractory plastic or refractory castable made of welded tile prefabricated block welding or with the material and refractory fiber felt on-site dressing. Life is generally 3 to 12 months. When the use of high-quality refractory plastic, ultra-low cement or cement-free refractory castables for field dressing, the life of more than la. Flue and smoke for their own use refractory lase lining generally with dry clay masonry, can also be used refractory castable prefabricated block hanging or on-site watering, and sometimes can be used refractory spray coating construction. Red brick or concrete chimney in high temperature area with refractory masonry. Metal chimney wall welding metal anchor nails, sometimes with metal mesh, the use of lightweight refractory castable or refractory spray for lining, construction convenience, integrity, long service life. (Refresable for rehea-ting fumace) Refractory materials used in masonry furnaces and related parts. The furnace is used for rolling or forging steel. Heating billet or small steel ingot thermal equipment, the use of the temperature is generally 13 of a 1 40. ℃.

This type of furnace is generally made of refractory clay brick masonry, heating section and soaking section roof is also useful 3-high aluminum brick 'lining damage is mainly due to high temperature, thermal stress, air erosion and mechanical collision caused by the role of high temperature The lower part of the furnace wall, the bottom of the furnace and the water-cooled tube packing layer and other parts are also affected by the erosion of molten iron oxide slag, therefore, masonry or mattress magnets for the protective layer, water pipe dressing layer with high alumina refractory. With the large-scale rolling mill and high efficiency, the heating protection made a higher demand, its development trend is large, low consumption, pollution-free and operational automation, building materials and therefore open and lift two The The door is generally made of clay brick, refractory castable or refractory plastic, high aluminum insulation brick or refractory fiber mats and other materials for lining.

Refractory material for refineries for rehea-ting fumace The refractory used in masonry furnaces and related parts The heating furnace is a thermal equipment used to heat billets or small billets when rolled or forged steel. Generally for a 13 of 13. ℃. This type of furnace is generally made of refractory clay brick masonry, heating section and soaking section roof is also useful 3 high aluminum refractory bricks' lining damage is mainly due to high temperature, thermal stress, air erosion and mechanical impact caused by such a high temperature The lower part of the furnace wall, the bottom of the furnace and the water-cooled tube packing layer and other parts are also affected by the erosion of molten iron oxide slag, therefore, masonry or paving magnesia for the protective layer, water pipe dressing layer with high alumina refractory.
