Abstract

The utility model relates to a middle billet cooling system for steel billets. The system consists of a power water supply pipeline, a PLC (Programmable Logic Controller) control system, upper and lower cooling water beams and an infrared temperature measuring device, wherein the water power supply pipeline is branched into four branch water supply pipelines; four cooling water beams are connected to each branch water supply pipeline; a group of flow control devices is arranged on each branch water supply pipeline; and the flow control devices are controlled by using the PLC control system. The cooling system is novel and reasonable in structure, has high automatic degree and high cooling accuracy, is low in maintenance cost, and can be applied to cooling before rolling of steel billets, steel plates and section steel in the metallurgical industry.

Description

The steel billet intermediate blank cooling system
Technical field
The utility model relates to the cooling system control structure before a kind of steel billet, steel plate, shaped steel rolling of metallurgy industry, relates in particular to a kind of steel billet intermediate blank cooling system.
Background technology
Steel billet from heating furnace out prepare feed mill rolling before because the requirement of steel grade and technique, it is could feed mill rolling to reach certain temperature, causes steel billet will treat temperature in air, like this so that rolling efficiency is low, the performance of enterprises is affected.
The utility model content
The utility model for overcome the above problems provide a kind of simple in structure, reduce time of staying temperature, improve the steel billet intermediate blank cooling system of rolling efficiency.
The technical solution of the utility model is: this system is by supply channel, PLC control system, up and down cooling water beam and infrared measurement of temperature degree device, tell four supply channels on the described supply channel, connect four cooling water beams on described each supply channel, on each supply channel one group of volume control device is set all, described volume control device is controlled by the PLC control system.
Described volume control device comprises electronic flowmeter, Pneumatic flow control valve and the pneumatic on-off valve that is successively set on the supply channel.
Be provided with on the pipeline of described lower cooling water beam and be adjusted to the long by-passing valve pipeline of opening state.
This system comprises that also one detects the infrared temperature measurement apparatus of steel billet temperature to be cooled, and this infrared temperature measurement apparatus transmission temperature information is to the PLC control system.
The utility model greatly reduces the time of staying temperature before the billet rolling; improved rolling efficiency; quality with steel plate; adopt and tell four supply channels on the main-supply road; and four cooling water beams of connection on each supply channel; these four groups prop up all be equipped with on the supply channel one the cover electronic flowmeter; Pneumatic flow control valve; pneumatic on-off valve; carrying out up and down four groups of cooling water beam segmentations independently controls; and be provided with on the pipeline of cooling water beam device under two groups and be adjusted to the long by-passing valve of opening state; when this cooling system is out-of-work, also can guarantee to be full of in the cooling water beam of bottom like this water always; so just can protect the water beam can not stopped up by the foreign material such as oxide skin that the nozzle on the high temperature billet steel of process baking distortion and the cooling water beam also is difficult for being dropped on the steel billet of top process; also be provided with an infrared temperature measurement apparatus in this device front portion; the temperature data that this infrared temperature measurement apparatus records is transferred to the PLC control system; the PLC control system is regulated the cooling required cooling water inflow of this steel billet and cooldown rate automatically according to this temperature data, has guaranteed like this cooling precision of this device.
This cooling system structure is new reasonable, and automaticity, cooling precision are high, and the maintenance operation cost is low, can be applicable to the cooling before steel billet, steel plate, shaped steel rolling of metallurgy industry.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is supply channel among the figure, the 2nd, and upper cooling water beam, the 3rd, lower cooling water beam, the 4th, electronic flowmeter, the 5th, Pneumatic flow control valve, the 6th, pneumatic on-off valve.
The specific embodiment
The steel billet intermediate blank cooling system, this system is by supply channel, the PLC control system, up and down cooling water beam and infrared measurement of temperature degree device, tell four supply channels on the described supply channel, connect four cooling water beams on described each supply channel, on each supply channel one group of volume control device is set all, described volume control device is controlled by the PLC control system, described volume control device comprises the electronic flowmeter that is successively set on the supply channel, Pneumatic flow control valve and pneumatic on-off valve, be provided with on the pipeline of described lower cooling water beam and be adjusted to the long by-passing valve pipeline of opening state, this system comprises that also one detects the infrared temperature measurement apparatus of steel billet temperature to be cooled, and this infrared temperature measurement apparatus transmission temperature information is to the PLC control system.
