Abstract
The invention relates to a cooling system for intermediate steel billets. The cooling system is composed of a water supply pipeline, a PLC control system, upper cooling water beams, lower cooling water beams and an infrared temperature measuring device, wherein the water supply pipeline is divided into four branch water supply pipelines, each branch water supply pipeline is connected with four cooling water beams and is provided with a set of flow control device, and the flow control devices are controlled by the PLC control system. The cooling system for the intermediate steel billets is novel and reasonable in structure, high in degree of automation and cooling precision, and low in maintenance and operation cost, and can be applied to cooling before rolling of steel billets, steel plates and structural steel in the metallurgical industry.
Description
Technical field
The present invention relates to a kind of steel billet, steel plate of metallurgy industry, the cooling system control structure before the rolling of shaped steel relates in particular to a kind of steel billet intermediate blank cooling system.
Background technology
Steel billet due to the requirement of steel grade and technique, must reach certain temperature ability feed mill rolling from heating furnace is out prepared feed mill rolling, causes steel billet will in air, treat temperature, makes like this rolling efficiency low, and the performance of enterprises is affected.
Summary of the invention
The present invention 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.
Technical scheme of the present invention is: this system is by supply channel, PLC control system, upper and lower cooling water beam and infrared measurement of temperature degree device, on described supply channel, separate four supply channels, on described each supply channel, connect four cooling water beams, on each supply channel, one group of volume control device is all set, described volume control device is controlled by PLC control system.
Described volume control device comprises electronic flowmeter, Pneumatic flow control valve and the pneumatic on-off valve being successively set on a supply channel.
On the pipeline of described lower cooling water beam, be provided with and be adjusted to the long by-passing valve pipeline of opening state.
This system also comprises the infrared temperature measurement apparatus of detection steel billet temperature to be cooled, and this infrared temperature measurement apparatus transmission temperature information is to PLC control system.
The present invention greatly reduces the time of staying temperature before billet rolling, improved rolling efficiency, quality with steel plate, on employing main-supply road, separate four supply channels, and connect four cooling water beams on each supply channel, at these four groups, prop up a set of electronic flowmeter is all installed on supply channel, Pneumatic flow control valve, pneumatic on-off valve, carrying out upper and lower four groups of cooling water beam segmentations independently controls, and under two groups, on the pipeline of cooling water beam device, be provided with 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 like this full of in the cooling water beam of bottom water always, so just can protect water beam can be not also difficult for being stopped up by the foreign material such as oxide skin that drop on the steel billet of top process by the nozzle on the high temperature billet steel of process baking distortion and cooling water beam, in this device front portion, be also provided with an infrared temperature measurement apparatus, the temperature data that this infrared temperature measurement apparatus records is transferred to PLC control system, PLC control system regulates the required cooling water inflow of cooling this steel billet and cooldown rate automatically according to this temperature data, guaranteed so the cooling precision of this device.
This cooling system structure is new reasonable, and automaticity, cooling precision are high, and maintenance operation cost is low, can be applicable to steel billet, the steel plate of metallurgy industry, cooling before the rolling of shaped steel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is supply channel, 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
Steel billet intermediate blank cooling system, this system is by supply channel, PLC control system, upper and lower cooling water beam and infrared measurement of temperature degree device, on described supply channel, separate four supply channels, on described each supply channel, connect four cooling water beams, on each supply channel, one group of volume control device is all set, described volume control device is controlled by PLC control system, described volume control device comprises the electronic flowmeter being successively set on a supply channel, Pneumatic flow control valve and pneumatic on-off valve, on the pipeline of described lower cooling water beam, be provided with and be adjusted to the long by-passing valve pipeline of opening state, this system also comprises the infrared temperature measurement apparatus of detection steel billet temperature to be cooled, this infrared temperature measurement apparatus transmission temperature information is to PLC control system.
