Background
At present, a smelting furnace for primary processing of refractory materials usually adopts a single-layer 6-10mm steel plate which is folded into a cylinder with the diameter of 1.2-2.5m as a furnace shell, and the smelting furnace is easy to deform due to single structure and has extremely low utilization rate.
In the sintering process of the smelting furnace, the molten slurry in the smelting furnace can penetrate through the preheating layer to leak the furnace shell under the influence of production operation technical errors or faults of relevant equipment such as electricity and the like. If the furnace shell is slightly leaked, the small holes are heavily leaked, and the furnace shell is completely cracked, molten slurry overflows, so that the scrapped yield of the furnace shell is lost. Not only has certain potential safety hazard, but also increases the production cost. In order to reduce the furnace shell consumption and the accident rate, manufacturers generally increase the thickness of the steel plate to alleviate the problems.
The smelting furnace usually takes about 180 hours from sintering to complete cooling, crushing and sorting, and the process is called a natural melting process. Because the furnace shell is a single-layer steel plate, the heat loss is too fast, so that the natural melting time is short, and crystals and the crystal orientation are not completely developed. Causing the phenomena of high proportion of the side products, low quality of the finished products, high power consumption and the like.

The outer furnace shell is composed of four arc-shaped plate shells of 4 th of a circle, two sides of each arc-shaped plate shell are provided with edge wings, the four arc-shaped plate shells are mutually butted, and adjacent edge wings are fixedly connected through bolts.
The inner wall of the outer furnace shell is provided with an anchoring piece, the outer wall of the inner furnace shell is provided with an anchoring piece, and the anchoring piece on the outer furnace shell and the anchoring piece on the inner furnace shell are arranged in a vertically staggered mode.
And reinforcing ribs are arranged on the outer wall of the inner furnace shell and are fixedly connected with the outer furnace shell.
The heat preservation furnace shell pouring layer is a refractory material pouring layer.
Compared with the prior art, the beneficial effects of the utility model are that:
1) the utility model discloses a pour layer, outer stove outer covering three parts with inlayer stove outer covering, heat preservation stove outer covering and combine together and have stronger tightness, can not warp basically.
2) The utility model discloses heat preservation stove outer covering three-layer gross thickness is close 150mm, and the layer is pour to good thermal shock stability magnesium-based composite in the middle of in addition. The furnace leakage and accident rate is reduced by more than 80%, thereby not only ensuring the production safety, but also saving certain cost.
3) The utility model discloses there is 60-120 mm's pouring layer furthest's prevention to melt the temperature loss of stone roller between inner shell and shell, provides the guarantee for natural melting and has reduced waste heat loss again and to atmospheric thermal pollution. The crystal orientation of the fused mound is arranged regularly, the crystal grains are full and thoroughly removed, the proportion of the auxiliary products is reduced, the quality and the grade of the finished product are greatly improved, and the power consumption is correspondingly reduced.
4) The equipment is energy-saving, environment-friendly and efficient, and can be popularized and applied in the primary processing smelting furnace of refractory materials.
