Description

Hot-strip is encrypted cooling device
Technical field
Hot-strip described in the utility model is encrypted the servicing unit that cooling device relates to smelter hot continuous rolling unit.
Background technology
Usually adopt band steel cooling facility for laminar flow that hot-strip is cooled off at present in the design hot continuous rolling unit, the steel grade of production is similar, has occurred serious supersaturation.Along with the continuous development of hot rolling technology and technology and user demand to premium quality product, the cooling velocity of hot-strip and the requirement of cooling uniformity are improved day by day, existing band steel cooling facility for laminar flow has not satisfied the process for cooling of producing high-strength steel, this research and design is gone out a kind of novel hot-strip encrypt cooling device, with original band steel cooling facility for laminar flow and usefulness, thereby cooldown rate and cooling uniformity have been improved, cooling system improves, and has improved the product quality and the market competitiveness.Because both shared identical water systems, hydraulic system and pneumatic system, equipment investment cost is very low, and this equipment may be used on the transformation of existing equipment equally.At existing problem in the above-mentioned prior art, a kind of novel hot-strip of research and design is encrypted cooling device, and existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is that a kind of novel hot-strip of research and design is encrypted cooling device, has not satisfied the process for cooling problem of producing high-strength steel thereby solve existing band steel cooling facility for laminar flow.
Hot-strip described in the utility model encrypt cooling device by last spray collector assemble, liquid level shows assembling, standpipe assembling, return bend assembling, the assembling of upset hydraulic cylinder, spray that collector assembles, by-pass valve control is formed down; Described standpipe mount is on the basis, one termination water system intermediate duct, the other end links to each other with the return bend assembling, and by-pass valve control is connected with the return bend assembling by adpting flange one end, the other end is connected with the assembling of last spray collector, on spray the collector assembling other end and connect liquid level and show and assemble; Upset hydraulic cylinder assembling drives the return bend assembling, comprises by-pass valve control, on spray collector assembling and liquid level and show that assembling turns round.Under spray collector assembling and be arranged between per two rollers of hot rolling runout table, link to each other with the water system intermediate duct by flexible pipe.A collector band four row's U-shaped pipes of going up in the assembling of spray collector described in the utility model, described U-shaped pipe latus rectum 20-25mm, jet pipe spacing 39-48mm, bore dia φ 8-12mm dams.Pipe racks two that catchments of the collector of spray down described in the utility model assembling is arranged jet pipe down, described jet pipe latus rectum 10-15mm, jet pipe spacing 51-68mm down.The nozzle of going up assembling of spray collector and following spray collector fitted with nozzles described in the utility model adopts the interlaced arrangement form.
The purpose that hot-strip described in the utility model is encrypted cooling device is that a kind of novel hot-strip of research and design is encrypted cooling device, thereby satisfying smelter and produce the special process for cooling requirement of high-strength steel grade. original band steel cooling facility for laminar flow only is fit to produce conventional steel grade, has problems such as cooling deficiency and inhomogeneous cooling for producing high-strength steel grade.Four row's U-shaped pipes are with in the spray collector assembling of going up that hot-strip described in the utility model is encrypted in the cooling device, under spray one of the collector assembling pipe racks two rows jet pipes down that catchment, and last spray jet pipe latus rectum 20-25mm, jet pipe spacing 39-50mm, bore dia φ 8-12mm dams, under jet pipe latus rectum 10-15mm, jet pipe spacing 51-68mm, readjust, avoid producing following situation: a) interference effect heat absorption mutually behind the water contact steel plate of adjacent jet pipe hypotelorism ejection, crossing cooling water far away distributes discontinuous along the steel plate width direction, the surface of steel plate that shuts out easily produces longitudinal stripe, influences product quality.B) throttle orifice size and U-shaped pipe latus rectum do not match and easily produce each U-shaped pipe to flow out the mass flow discrepancy of cooling water even, can occur drip or cutout phenomenon individually, do not satisfy the big flow of low-pressure of technological requirement.C) arrange two row's jet pipes owing to spray collector under every, and the cooling water that two row's jet pipes are avoided spraying is interfered mutually should guarantee enough intervals, can make down the excessive of collector pipe design like this, cause the too small heat exchange effect that influences of the cooling water heat swapace that is surrounded with steel plate and roller, adopt two row's jet pipe interlaced arrangement, problem is resolved.Because identical cooling section jet pipe quantity is reasonably increased.And forming many row's jet pipe mutual dislocation arranges, therefore encrypt along the layout of strip width direction jet pipe, improved the uniformity of broad ways cooling, and because the increase of jet pipe number, satisfying the also corresponding increasing of cooling water inflow under the big flow prerequisite of low-pressure, cooldown rate is improved thus.Encrypt cooling device owing in the intermediate duct that links to each other, electric control valve has been installed for fine setting, cooperate electromagnetic flowmeter can realize that flow regulates automatically, thereby guaranteed to produce the special process requirement of high-strength steel.
The utlity model has novel structure, be easy to processing and manufacturing, install adjust and change easy, save cost, advantage such as safe and reliable, coming into operation, the back produces high-strength steel grade cooldown rate for smelter and cooling uniformity can be significantly improved, thereby the comprehensive mechanical performance of product is guaranteed, improve competitiveness of product, will produce positive social benefit and remarkable economic efficiency.
