Trolley-type resistance furnace

First, the use of trolley resistance furnace
All-fiber trolley resistance furnace is a cycle furnace, a large industrial furnace, mainly for the general large, medium-sized castings or alloy parts at rated temperature for heat treatment purposes.

Second, trolley resistance furnace structure
The car furnace by the furnace (including furnace lining), door, furnace car, door lifting mechanism, carriage traveling agencies, heating elements, temperature control system, temperature records and other components.
The furnace body for the steel structure, the steel skeleton welded by steel, steel, etc., the entire steel structure design is reasonable, solid structure.
The heating element is made of Shougang high-resistance alloy 0Cr25Al5 resistance band arranged in the furnace door, furnace side, behind the furnace wall and trolley.
Lining with large fiber plate structure hanging in the steel skeleton, the load-bearing part of the use of heavy refractory brick masonry, in order to enhance the structural strength of the lining. Trolley insulation with aluminum silicate refractory fiber, diatomite insulation composite energy-saving structure, in order to improve the thermal insulation energy-saving performance.

2, furnace steel structure:
The outer wall of the furnace, between the columns and between the top of the column are all pulled by the steel to form a grid structure, which is more safe and reliable than the traditional refractory brick furnace in rigidity and stability. Weld uniform formation, no pores, slag, cracks, unfinished defects, the appearance of straight, smooth, no wrinkles uneven phenomenon.

3, part of the furnace insulation:
Furnace insulation part of the whole fiber structure, the selection of the current domestic high-purity 1260 ceramic fiber blanket as the furnace insulation materials, insulation thickness of 260mm.
The fiber blanket is an artificial inorganic metal fiber material. In the 20th century, the United States was the first to use it on a heating furnace. Because of its excellent performance, all the advanced countries have developed and used it. In the 1990s, China got more popularization and application, Fully mature and reliable. In recent years, my company has stepped up technological development in this area, for many users have produced a variety of series of nearly 100 sets of fiber-optic industrial furnace, which has electric furnace, gas furnace, oil furnace and so on.
Production using special equipment will be 220kg / m3 fiber blanket according to the size of the hearth compression folded into folded fiber plate, and in the process of leaving a certain amount of compression to ensure that the collapse of the block after the completion of the furnace, each piece of ceramic The fiber blocks expand in different directions, so that the folded blocks are mutually squeezed into a whole without gaps to reach the intact heat storage effect, and the anchor is arranged on the cold surface of the furnace body to improve the high temperature resistant strength of the fiber.
Bottom of the load-bearing part of the insulation layer with diatomaceous earth insulation brick, refractory clay refractory composed of standard refractory, heavyweight part of the heavy aluminum brick.
