Embodiment Construction

[0013] like figure 1 The roof of a steel-clad belt-type pellet energy-saving roasting furnace shown includes: a hanging pipe 1, a hanging piece 2, an insulation layer 3, an anchor brick 4, and a furnace roof pouring material 5; the hanging pipe 1 is embedded horizontally In hanger 2.

[0014] The thermal insulation layer 3 is outside the topmost anchor brick 4 .

[0015] The anchor brick 4 is the joint between the layers.

[0016] The furnace top pouring material 5 is connected with the insulation layer 3 .

[0017] The working principle of the roof of Baotou steel belt-type pellet energy-saving roasting furnace of the present invention is to prolong the service life of the furnace roof, reduce the maintenance time, increase the output of pellets, and at the same time to better control the roasting temperature of each stage of pellets , Added 6 temperature measuring points on the top of the furnace. Based on the above reasons, the roof-hanging brick masonry was changed to ...

Abstract

The invention discloses a Baotou Steel belt-type pellet energy-saving furnace roof, which is characterized in that the furnace roof comprises a suspension pipe, a hanger, a heat-insulation layer, an anchoring brick and a castable, wherein, the suspension pipe is embedded in the hanger transversally. The Baotou Steel belt-type pellet energy-saving furnace roof has the advantages that the furnace roof service life can be prolonged; the unkeep time can be reduced; the pellet ore yield can be increased; at the same time, to grasp the roasting temperature in each phase, 6 temperature measurement points are added. Therefore, the structure of masonry by hanging bricks on the furnace roof is changed to cast the furnace roof by hanging anchor brick in combination with low cement high-strength castable material. The advantages are that the construction is simple; the service life is long; the integral performance is good; the intensity is high; and the local unkeep is convenient.

Description

technical field [0001] The invention relates to a furnace roof of a roasting furnace, in particular to a steel-clad belt-type pellet energy-saving roasting furnace roof, which belongs to the field of mineral equipment. Background technique [0002] The roof of the existing roasting furnace is made of hanging bricks. Generally, after one year of use, the roof is burned to varying degrees, and bricks are partially dropped and the roof is caught on fire. Therefore, the roof is often repaired. The furnace roof hanging brick structure must be overhauled after three years of use. The existing roof of the roaster needs long-term detection and frequent maintenance, and its service life is short, which makes the output of pellets low. Therefore be badly in need of a kind of production and construction simple and convenient, long service life, overall performance is good, intensity is high, the roasting furnace roof that partial maintenance is convenient. Contents of the invention ...
