Gate Valve For Steel Smelting:
- How it works: The gate inside goes up and down to open or close the pipe. It’s made to match the full pipe size, and the seal uses either hard metal or flexible material.
- Key features: Hardly any resistance to fluid flow. Handles high heat and pressure really well. – Where to use it: Blast furnace gas pipes, converter gas recovery systems.
- What it can handle: Takes up to 1,500°C high heat. Used to stop molten metal or hot gas from flowing.
Ball Valve For Steel Smelting:
- How it works: There’s a ball inside that turns 90 degrees to open or close. Some have special alloy on the ball to resist wear.
- Key features: Opens and closes fast—just a 90-degree turn. Low fluid resistance. 3 times more wear-resistant than regular ones.
- Where to use it: Oxygen pipes for oxygen top-blown converters. – What it can handle: Deals with 2.5MPa pressure. Works in temps from -40°C to 600°C, even with big temp changes.
Butterfly Valve For Steel Smelting:
- How it works:
A flat “butterfly” piece inside spins to control flow. It’s simple, small, and light.
- Key features:
Easy to adjust flow. Good for big pipes. Can use air to move it for quick changes.
- Where to use it:
1.High-temp butterfly valves: Used in sintering machine flue gas desulfurization systems.
- Air butterfly valves: Used in blast furnace blower inlet pipes.
- What it can handle:
1.Takes 220°C acidic gas without rusting easily.
- Needs to adjust air flow, so it uses air to work.
Globe Valve For Steel Smelting:
- How it works:
A plug seals tight against a seat. Fluid has to change direction to get through.
- Key features:
Seals really well, but fluid faces more resistance. Can have special designs for specific needs.
- Where to use it:
1.Insulated globe valves: Used in cooling water systems for continuous caster molds.
2.Oxygen-specific globe valves: Used in oxygen pipes for stainless steel cold rolling.
- What it can handle:
1.Has a jacket design to keep water warm—stops steel from hardening.
2.Uses no oil lubrication—keeps oxygen clean, no rust bits.
Check Valve For Steel Smelting:
- How it works: Also called a “one-way valve.” Fluid pressure opens it, and it stops fluid from flowing back. Two common types: lift-up and swing-up.
- Key features:
No extra power needed. Reduces water hammer risk. Stops gunk from sticking.
- Where to use it:
1.Quiet check valves: Used in steelmaking circulating water pump stations.
2.Double-disc check valves: Used in coke oven gas pipes.
- What it can handle:
1.Cuts water hammer pressure by 60% to protect pipes.
2.Stops tar from sticking, so it needs less fixing.
Blind Valve For Steel Smelting:
- How it works: Has a valve body, a blind plate, and a screw. Turn the screw to move the plate—opens or shuts the pipe.
- Key features: Seals very tight. Good for repair work. Electric ones work fast.
- Where to use it: Gas pipe repairs (to shut off gas).
- What it can handle: Electric types use gears to shut fast, which saves repair time.
Control Valve For Steel Smelting:
- How it works: Has a “mover” part and a valve body. Gets signals to change how open it is.
- Key features: Controls flow, pressure, and temp precisely. Smart ones use math to stay accurate.
- Where to use it: Smart control valves are used in blast furnace coal injection systems.
- What it can handle: Keeps coal powder flow steady—only a ±1% change. Cuts energy use by 12%. Relief Valve
- How it works: Uses a spring or weight. If pipe pressure gets too high, it opens automatically. Lets extra gas or liquid out.
- Key features: Keeps pipes safe (stops overpressure). Works on its own.
- Where to use it: Top of the blast furnace gas riser pipe.
- What it can handle: Lets out extra blast furnace gas when pressure is too high.
ZZJG VALVE supply steel smelting valves, including ball valve, butterfly valve, gate valve, check valve, globe valve, control valve, blind valve. In a nutshell, as follows:
1.Material stuff: For steel smelting, valves use materials that handle heat and rust—like special alloys on ball valves, hard metal seals on gate valves. They’re good for hot, dirty, or corrosive things (like gas or acidic smoke).
2.Safety & efficiency:
- Check valves (quiet, anti-stick) and relief valves (auto-release) stop accidents—like water hammer, explosions, or clogs.
- Blind valves (fast shut-off) and control valves (precise flow) keep work safe and fast—shorter repair times, less energy use.
3.How to move them: Some use hands (simple jobs), some use air (needs quick adjustments, like blower valves), some use electricity (needs fast or remote control, like blind valves). Smart control valves even use auto programs—good for automated lines.
