Description
The utility model relates to a kind of mixing cooling tubular continuous casting mould, belongs to the metal bloom continuous cast mold.
Tubular continuous casting mould of the prior art can be divided into two kinds of water flowing cooling and spray coolings.Water flowing cooling tubular continuous casting mould mainly is made up of copper pipe, water conservancy diversion water jacket, water tank and last lower flange etc.Cooling water flows into from the bottom water tank, and under pressure, by evenly passing through from bottom to top in the water conservancy diversion water jacket, cooling copper tube makes the molten steel scull, flows out through water tank upper, and it is cold to belong to laminar heat transfer.The heat flow density that copper pipe is gone up along its length changes, and laminar heat transfer, the intensity of cooling water is the same, cooling water usually can produce aerosol membrane in the boiling of meniscus district, makes heat transfer efficiency reduce.If the gap between water conservancy diversion water jacket and the copper pipe outer wall, owing to reasons such as manufacturing, installations, produce inconsistently, when causing intensity of cooling difference, often cause chink, off-square or bleed-out.In addition,, need to adopt demineralized water, increased cooling cost for preventing that generating incrustation scale at the copper pipe outer wall influences heat-transfer effect.
Chinese patent CN92222292.4 discloses a kind of spray cooling tubular continuous casting mould.On the basis of former water flowing cooled crystallizer, remove the water conservancy diversion water jacket, mist adds an outer water jacket outside water tank, constitutes intercalated water sleeve with the raw water box outer wall.On the inwall of raw water box nozzle carrier is installed, the nozzle of different flow is installed on the nozzle carrier, cooling water passes through the inlet opening under certain pressure, enter intercalated water sleeve, spray to the copper pipe outer wall, under atmospheric pressure fall naturally afterwards by nozzle, flow out through delivery port, belong to jet and go out the cooling of conducting heat.The high speed cooling water of nozzle ejection to the percussion of copper pipe outer wall, both had been easy to break the aerosol membrane that the cooling water boiling of meniscus district produces, and prevented the generation of incrustation scale again, and heat transfer efficiency is higher.The intensity of cooling of cooling water is pressed the heat flow density size reasonable distribution that copper pipe conducts heat, and copper pipe is conducted heat evenly.Replace demineralized water with water purification, reduced cooling cost.Existing weak point is: on copper pipe top, after the rapid and strong cooling, produce air gap between strand and copper pipe inwall, stop copper pipe outwards to conduct heat, make the high-velocity flow of lower nozzle ejection can not bring into play due efficient, cause the waste of cooling water.Because the deposition of the impurity in the cooling water easily causes lower nozzle to stop up, be difficult to cleaning in addition, increased maintenance cost.
The purpose of this utility model provides a kind of mixing cooling tubular continuous casting mould, laminar heat transfer cooling and jet impulse heat transfer cooling are combined, make distribution of crystallizer intensity of cooling and structural design more reasonable, further improve cooling effectiveness, save cooling water, and make it be easy to safeguard.
The purpose of this utility model is to realize like this.At crystallizer middle part, a dividing plate that is connected with tank inner wall is arranged between copper pipe and the water tank, dividing plate and copper pipe touching position are equipped with sealing ring; The water conservancy diversion water jacket is arranged on below the dividing plate, and supporting is fixed on the water tank; Install more than the panel seat, the outer water jacket in the water tank outside and water tank constitute the spray water tank; The nozzle of different flow is housed by nozzle carrier on the dividing plate upper tank inwall; Have on the water tank wall between dividing plate and the water conservancy diversion water jacket and spray the hole that water tank communicates; Water inlet is arranged on the water tank bottom, and delivery port passes outer water jacket and is arranged on the water tank intermediate membrane.Dividing plate is with the cooling system separated into two parts of crystallizer, and top is the spray cooling, and the bottom is the water flowing cooling.
The spray type of cooling is adopted on top, and the high speed cooling water of nozzle ejection is easy to break the aerosol membrane that the cooling water boiling of meniscus district produces to the percussion of copper pipe outer wall, and prevent that incrustation scale from producing, the heat transfer efficiency height makes copper pipe obtain rapid and balanced cooling, has obviously encouraged the formation of base shell.But simultaneously, between strand and copper pipe inwall, produce air gap, the copper pipe heat transfer efficiency is descended, along with after blank enters bottom water flowing cooling system, the reduction of intensity of cooling, strand expands under the effect of liquid heart heat, and air gap dwindles, the heat transference efficiency recovery of copper pipe.Just entered the low-temperature cooling water of water tank this moment, copper pipe is produced time strong cold-working usefulness, produced the gap between strand and the copper pipe once more, the efficient of cooling water is fully played.The top spraying cooling water is the reusing of cooling water in the lower guide flowing water cover, but owing to progressively reduce from the following heat flow density in meniscus district, so by after the water conservancy diversion water jacket, temperature rise can be very not high, do not influence the cooling effect of top spray system.Cooling water temperature rise is lower simultaneously, also is difficult for fouling on copper pipe.
The advantage that the utility model is compared with prior art had is: 1. the first half adopts the spray type of cooling, Lower Half adopts the water flowing type of cooling, the intensity of cooling of cooling water is distributed by the heat flow density size reasonable that copper pipe conducts heat, cooling evenly, the efficient of cooling water is fully played, the intensity of cooling height; 2. because the top spraying cooling water is reusing of bottom water flowing cooling water, the actual used water amount only is top spray water consumption, compares cooling water amount with spray cooling tubular continuous casting mould and can save 50%; Since cooling evenly, the intensity of cooling height is compared with the casting machine that adopts spray cooling tubular continuous casting mould and can be made casting speed improve more than 10%; 4. avoided former spray cooling tubular continuous casting mould on the structural design, because the lower nozzle clogging that the impurity deposition causes in the cooling water is easy to safeguard.
