Problems solved by technology
Due to the low processing accuracy requirements of the spliced and formed insulation cylinder and the insulation cylinder frame, there are inevitably gaps in the spliced and formed insulation cylinder, which greatly reduces the insulation performance and uniformity, and the disassembly and assembly of the insulation cylinder is very cumbersome. Too many bolts make maintenance inconvenient
Therefore, the existing heat preservation cylinder structure is becoming less and less suitable for the uniformity of the temperature field of the sintering furnace and the gentleness of the temperature rise and temperature drop curve. The disassembly and assembly are too cumbersome and not conducive to later maintenance.

The embodiment of the invention provides a square heat preservation cylinder. The square heat preservation cylinder comprises a heat preservation cylinder body, an upper fixing frame and a lower fixing frame which are integrally formed. The heat preservation cylinder body comprises four fixed panels and four chamfered panels, wherein every two adjacent fixed panels are connected through one chamfered panel, so that the section of the heat preservation cylinder body is square and is provided with a chamfered structure, a first preset number of first bolt holes 14 are formed in each fixed panel,and the upper fixed frame and the lower fixed frame are respectively fixed with the fixed panels through first bolts. The integrally-formed heat preservation cylinder is free of splicing gaps, the strength and the heat preservation performance are improved, the requirements for sintering furnace temperature field uniformity and temperature rising and falling curve smoothness can be met, later maintenance is facilitated, the heat preservation performance of the heat preservation cylinder is improved, meanwhile, the maintenance cost is reduced, and more resources are saved.
Description
technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a square heat preservation cylinder. Background technique [0002] With the vigorous development of my country's metallurgical industry, there are higher requirements for metallurgical equipment, among which higher requirements are put forward for the thermal insulation performance of the thermal insulation cylinder. Due to the consideration of cost control, the integrated vacuum sintering furnace needs to use a square insulation cylinder structure, but the ability of the square insulation cylinder structure to resist deformation is much worse than that of a round insulation cylinder, which requires a high-strength frame outside the insulation cylinder And through the locking of the CFC fixing bolts, the strength of the insulation cylinder is improved to ensure that the insulation cylinder does not undergo serious deformation during the rapid heating and cooling o...
