Abstract

The utility model discloses a rolling steel heat preserving cover which comprises a cover body. The cover body comprises an outer layer and an inner layer. A heat preserving layer is disposed between the outer layer and the inner layer. The cover body is in a hollow cylinder shape, and a plurality of through grooves are disposed at intervals on a lower portion of the cover body. The rolling steel heat preserving cover is disposed on a roller way for steel transportation, can increase finishing rolling temperature of steel products, improves product quality, and is easy to manufacture and low in cost. When being used, the rolling steel heat preserving cover is placed on a mounting bracket near the rolling way, and for the steel products with no need for heat preserving, the rolling steel heat preserving cover can be taken down. Therefore, the rolling steel heat preserving cover is convenient to use.

Description

The steel rolling stay-warm case
Technical field
The utility model belongs to technical field of steel rolling, particularly relates to a kind of steel rolling stay-warm case that is used for the steel transportation.
Background technology
Temperature is the important control factor of steel rolling industry, and the control of rolling temperature directly has influence on rolling quality, rolling waste product and rolling cost.For some thermally sensitive steel grade; For example austenitic stainless steel or dual phase steel, if rolling temperature is low excessively, can occur rolling split, rolling load increases, equipment loss increases, rolling lumber recovery descends; And might not reach the mill product size of initial equipment, cause waste product in batches.
Domestic majority producer adopts the mode of reheating furnace or increase eddy-current heating to improve finishing temperature traditionally, but this dual mode floor space is big, requires to have enough device spaces, and this is difficult to realize for the factory building of having finalized the design; Have high input, cost is high; Energy consumption is high, needs more gas consumption or power consumption; Waste of manpower, and need manually-operated.
The utility model content
The technical problem that the utility model will solve provide a kind of make simple, cost is low, easy to use, the steel rolling stay-warm case that can improve the steel finishing temperature, improve the quality of products.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of steel rolling stay-warm case comprises cover body, and cover body comprises skin, internal layer, between the inside and outside layer heat-insulation layer is set, and cover body is a hollow cylinder, and the bottom of cover body is provided with a plurality of grooves at interval.
The utility model steel rolling stay-warm case wherein also comprises burner, and a side at the top of cover body is provided with through hole; The port of export of burner inserts in the through hole, and burner is provided with baffle ring, and baffle ring is stuck in around the through hole; The other end of burner is provided with fuel gas inlet, and the burner middle part also is provided with air intlet.
The utility model steel rolling stay-warm case, the wherein said outer steel that adopt are processed.
The utility model steel rolling stay-warm case, wherein said internal layer adopt steel to process.
The utility model steel rolling stay-warm case, wherein said heat-insulation layer adopt asbestos or ceramic fibre as heat insulating stuffing.
The utility model steel rolling stay-warm case, the quantity of wherein said burner are 1-2, and burner tilts to insert in the through hole.
The utility model steel rolling stay-warm case is increased on the steel conveyor roller, can improve the finishing temperature of steel, has improved product quality; It makes simple, and cost is low, is supported on during use near the carriage of roller-way; For the steel that need not be incubated, can stay-warm case be taken off, easy to use.
Be described further below in conjunction with the steel rolling stay-warm case of accompanying drawing the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model steel rolling stay-warm case user mode;
Fig. 2 is the cutaway view of the utility model steel rolling stay-warm case user mode.
The specific embodiment
Like Fig. 1, shown in 2; The utility model steel rolling stay-warm case comprises cover body 1, burner 2; Cover body 1 comprises skin 11, internal layer 12, and outer 11 adopt steel to process, and internal layer 12 adopts steel or other reflection thermal source preferred metal to process; Between the inside and outside layer heat-insulation layer 13 is set, heat-insulation layer 13 adopts asbestos or ceramic fibre etc. as heat insulating stuffing.Cover body 1 is a hollow cylinder, and the bottom of cover body 1 is provided with a plurality of grooves 14 at interval, and the quantity of groove 14 equates with roller-way 3 quantity on cover body 1 length direction, a roller-way only is shown among the figure.
One side at the top of cover body 1 is provided with through hole, and the port of export of burner 4 tilts to insert in the through hole 15, and burner 4 is provided with baffle ring 41, and baffle ring 41 is stuck in around the through hole, prevents that burner 4 from dropping.The other end of burner 4 is provided with fuel gas inlet 42, and burner 4 middle parts also are provided with air intlet 43.
The utility model steel rolling stay-warm case is increased on bar, sheet material or the steel pipe conveyor roller, is supported by carriage 5 during use, and roller-way 3 is positioned at groove 14 during placement; Steel pipe 6 is positioned at stay-warm case, is carried by a plurality of roller-ways, through the stay-warm case of the utility model; Can improve the finishing temperature of steel,, can stay-warm case be taken off for the steel that need not be incubated; Step is simple, and is workable.This stay-warm case has reduced production process, reduces production costs, improves the quality of products, and has reduced the rolling defect of being brought by temperature drop.
About 3 meters of the utility model steel rolling stay-warm case length according to conveyor roller length, can be placed a plurality of steel rolling stay-warm cases.
The utility model steel rolling stay-warm case top is provided with burner, and 1-2 burner can be set on each stay-warm case, can be through lighting flame in fuel gas inlet, for increasing heat in the stay-warm case in the use.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
