According to the utility model, a suspended-type heat preservation cover is arranged above the cold bed, the cooling speeds of rolled pieces with different steel grades and specifications in different temperature ranges can be controlled through comprehensive measures such heat preservation covers in different regions as well as the opening and the starting of a heat insulation door, the requirements of cooling process to rolled steel in different steel grades and specifications can be met, on-line cooling control to the temperature of rolled pieces is achieved, the mechanical property of products is improved, the rejection rate and the defective rate are reduced greatly, the manufacturing cost is lowered, and economic benefits are increased.
Description
Technical field
The utility model relates to a kind of attemperator, relates in particular to a kind of cold bed attemperator.
Background technology
Along with the fast development of industries such as machinery, automobile, military project, market increases high added value bar product demand such as pinion steel, alloy spring steel, bearing steel, stainless steel, mould steels day by day.In this series products, the content of alloying elements such as carbon and Cr, Ni, Mn, V is higher, and in cooling procedure, cooling velocity is too fast, and structural stress that phase transformation and variations in temperature cause and thermal stress cause rolled piece surface and inside to crack easily.Simultaneously, STRESS VARIATION also can influence the diffusion of protium in the rolled piece, in rolled piece, is prone to form " white point " defective, thereby causes substandard products and waste product.
Different steel grades and specification rolled piece all have strict process for cooling; Be that rolled piece needs different cooling velocities in the different temperatures interval; And traditional conventional cold bed (stand) can not adapt to the production demand; Especially for the rolled piece that needs slow cooling, collect fast, easily scuffing is caused on high temperature rolled piece surface though conventional plug-type cold bed can be realized the slow cooling material; Though conventional walking beam cooler can to a certain degree realized big specification slow cooling material collection through accelerating stepping period, the centering small dimension is as collecting powerless less than Φ 60mm rolled piece high temperature.
The utility model content
The purpose of the utility model is to provide a kind of cold bed attemperator that can control rolled piece in the interval cooling velocity of different temperatures.
The purpose of the utility model is to realize like this; A kind of cold bed attemperator; It is characterized in that: the cold bed both sides are provided with main body rack; Said main body rack is provided with lowering or hoisting gear and is positioned at the top of said cold bed, and said lowering or hoisting gear is divided on hanging beam and the said hanging beam and hung stay-warm case, can or fall with the lowering or hoisting gear rise.
Also be provided with the supporting track that supports above-mentioned stay-warm case on the aforementioned body support.
Above-mentioned supporting track below is provided with thermal insulating door thermally insulated door, can regulate the insulation case temperature through the open and close of thermal insulating door thermally insulated door.
Aforementioned body support, supporting track, stay-warm case and thermal insulating door thermally insulated door inboard are equipped with heat preserving and insulating material.
Above-mentioned cold bed top is provided with 1-50 lowering or hoisting gear.
1-50 thermal insulating door thermally insulated door is set around the above-mentioned cold bed.
When rolled piece need adopt quick cooling, the stay-warm case of being located at the cold bed zone was through lowering or hoisting gear and all or part of rising of hanging beam.At this moment, stay-warm case and supporting track break away from, and the height of stay-warm case and supporting track can be regulated according to technological requirement, all or part of the opening of thermal insulating door thermally insulated door of supporting track below, and its unlatching can be regulated according to technological requirement.Rolled piece gets into cold bed through rollgang, the cold bed regional opening, and cross-ventilation increases, and heat radiation is very fast, and rolled piece has lower collection temperature, thereby reaches cold soon.
When rolled piece need adopt slow cooling, stay-warm case was through lowering or hoisting gear and all or part of decline of hanging beam.At this moment, stay-warm case is positioned on the supporting track, all or part of the closing of thermal insulating door thermally insulated door of supporting track below, and it is closed and can regulate according to technological requirement.Rolled piece gets into cold bed through rollgang, the sealing of cold bed zone, and cross-ventilation weakens, and the rolled piece heat radiation is slow, and rolled piece has higher collection temperature, thereby reaches slow cooling.
The utlity model has following beneficial effect; The utility model is provided with the suspension type stay-warm case above cold bed; Comprehensive means such as the unlatching through zones of different stay-warm case, thermal insulating door thermally insulated door and closure are controlled different steel grades, specification rolled piece in the interval cooling velocity of different temperatures, can satisfy the process for cooling requirement of different steel grades and specification steel rolling, have realized that the online cooling of rolled piece temperature is controlled; Improved the product mechanical performance; Reduce percent defective and defect rate significantly, reduced production cost, promoted economic benefit.

The specific embodiment
Embodiment, a kind of cold bed attemperator, cold bed 2 sides are provided with main body rack 3, and main body rack 3 is provided with lowering or hoisting gear 5 and is positioned at the top of cold bed 2, and lowering or hoisting gear 5 is divided into hanging beam 6, suspension stay-warm case 7 on the hanging beam 6; Also be provided with the supporting track 4 that supports stay-warm case 7 on the main body rack 3, supporting track 4 belows are provided with thermal insulating door thermally insulated door 8.Main body rack 3, supporting track 4, stay-warm case 7 and thermal insulating door thermally insulated door 8 inboards are equipped with heat preserving and insulating material.1-50 lowering or hoisting gear 5 can be set on the cold bed 2, around the cold bed 2 1-50 thermal insulating door thermally insulated door 8 can be set.
When rolled piece need adopt quick cooling; The stay-warm case 7 of being located at cold bed 2 zones is through lowering or hoisting gear 5 and hanging beam 6 all or part of risings; At this moment, stay-warm case 7 breaks away from supporting track 4, and stay-warm case 7 is regulated according to technological requirement with the height of supporting track 4; Thermal insulating door thermally insulated door 8 all or part of the opening of supporting track 4 belows, its unlatching can be regulated according to technological requirement.Rolled piece gets into cold bed 2 through rollgang 1, cold bed 2 regional openings, and cross-ventilation increases, and heat radiation is very fast, and rolled piece has lower collection temperature, thereby reaches cold soon.
When rolled piece need adopt slow cooling; Stay-warm case 7 is through lowering or hoisting gear 5 and hanging beam 6 all or part of declines, and at this moment, stay-warm case 7 is positioned on the supporting track 4; Thermal insulating door thermally insulated door 8 all or part of the closing of supporting track 4 belows, it is closed and can regulate according to technological requirement.Rolled piece gets into cold bed 2 through rollgang 1, cold bed 2 zone sealings, and cross-ventilation weakens, and the rolled piece heat radiation is slow, and rolled piece has higher collection temperature, thereby reaches slow cooling.
