Description
Technical field:
The utility model relates to the thermal straightening machine structure, particularly thermal straightening machine roll surface gas-mist cooling device.
Background technology:
Steel rolling working roll of hot straightening machine face is under hot soak condition, and high-temerature creep easily occurs, heat fatigue cracking, thus cause the surface quality defect of straightening steel plate, therefore, be quite necessary to the cooling of working roller of straightening machine face.Its cooling device is the cooling collection comb that is arranged in parallel between working roll and backing roll in the roller box, several nozzles is installed towards the working roll roll surface on the collection comb.Cooling medium realizes that by the working roll that nozzle sprays to rotation roll surface is cooling.At present, the cooling water spray that generally adopts of domestic working roll of hot straightening machine face is cooling, to reduce the working roll surface temperature, aligns roll surface thereby protect.
Existing water cooling plant is comprised of water inlet flow channel, master control valve, collection comb.Water inlet flow channel is that water source tube is communicated with main road runner, bypass runner by threeway, and the main road runner is communicated with by pipeline successively by front ball valve, water route pressure-reducing valve, rear ball valve, water route check valve, and water pressure gauge also is installed on the main road runner.By threeway and water route check valve inlet end pipeline connection, the water route check valve delivery port of water inlet flow channel is by master control valve and collection comb water inlet pipeline connection by the bypass ball valve for the bypass runner.The collection comb be that some row's transverse tubes are installed between two longitudinal tubule (L tubule)s, under every transverse tube along uniform several nozzles of face.When main road runner fault or maintenance, close the main road runner, open the bypass runner.
The defective of this water cooling plant is: full Artificial Control is unfavorable for monitoring automatic control.Adopt simultaneously water spray cooling, inhomogeneous cooling is even, and has a large amount of water and accumulate on the hot surface of steel plate of aligning, causes the local temperature drop of steel plate, makes its performance that serious variation will occur, brings very large difficulty to the quality control of production board.
Summary of the invention:
The purpose of this utility model is to overcome defects, and a kind of thermal straightening machine roll surface gas-mist cooling device is provided.
The utility model scheme is: the water inlet flow channel, master control valve, the collection comb that comprise water cooling plant, it is characterized in that: be connected in series a magnetic valve on pipeline between the water route pressure-reducing valve of water inlet flow channel main road runner and rear ball valve, described magnetic valve lead-in wire port is communicated with the PLC central processing unit output circuit of setting up; Set up a gas circuit runner, the gas circuit runner is successively by gas source pipe, gas circuit ball valve, air passage one-way valve, gas circuit pressure-reducing valve pipeline connection; An atomizer is set, the water route check valve delivery port of water inlet flow channel and atomizer water inlet pipeline connection, the gas circuit pressure-reducing valve gas outlet of gas circuit runner by threeway respectively with air gauge, atomizer air intake pipeline connection; The mist exhausting port of atomizer is by master control valve and collection comb water inlet pipeline connection; A heat inspection device is installed, heat inspection device information output and PLC central processing unit input connection above straightener front end roller-way.
The utility model has the advantage of: the water content in the aerosol of aligning work roll surface can realize automatic control, cooling evenly, not having that ponding accumulates is on the working roll of hot straightening machine face.Atomizer structure is simple, easy to manufacture simultaneously, and bug check is easy, and is easy to maintenance, also is applicable to other occasion.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the atomizer structure schematic diagram.
The specific embodiment:
The utility model structure: the water inlet flow channel, master control valve 10, the collection comb 12 that comprise water cooling plant, it is characterized in that: be connected in series a magnetic valve 2 on pipeline between the water route pressure-reducing valve 1 of water inlet flow channel main road runner and rear ball valve 4, described magnetic valve 2 lead-in wire ports are communicated with the PLC central processing unit output circuit of setting up; Set up a gas circuit runner, the gas circuit runner is successively by gas source pipe 11, gas circuit ball valve 6, air passage one-way valve 7, gas circuit pressure-reducing valve 8 pipeline connections; An atomizer 9 is set, water route check valve 5 delivery ports of water inlet flow channel and atomizer 9 water inlet 91 pipeline connections, gas circuit pressure-reducing valve 8 gas outlets of gas circuit runner by threeway respectively with air gauge, atomizer 9 air intake 92 pipeline connections; The mist exhausting port 93 of atomizer 9 is by master control valve 10 and collection comb 12 water inlet pipeline connections; A heat inspection device 3 is installed, heat inspection device 3 information outputs and PLC central processing unit input connection above straightener front end roller-way.
Atomizer 9 is standard component, L shaped tracheae transverse pipe is in the center of a horizontal shaped telescopic tube hollow, transverse pipe front end muzzle has nozzle, the longitudinal pipe cylindrical of L shaped tracheae is sealed passes horizontal shaped telescopic tube tube wall, L shaped tracheae upper port is water inlet, and laterally the shaped telescopic tube front and back end ports is fixed with respectively air intake, the mist exhausting port of tubulose.
Control system detects by heat inspection device 3 before being installed at straightener the PLC central processing unit that the front steel billet temperature signal of aligning reads in operating desk, the program that weaves automatically judge time that in this device of this temperature range, magnetic valve 2 is opened and interval time length, the aerosol water content and the volatile quantity that are sprayed on the work roll surface with control balance each other, during this time by the short-term self-learning function, constantly revise aerosol process for cooling parameter, can realize that the cooling water nil product at surface of steel plate is stayed when straightening steel plate, reach again the purpose of cooling work roll surface simultaneously.
