Abstract

A broken belt cooling device for a continuous annealing furnace is mainly used for cooling a broken belt at an inlet of the continuous annealing furnace for cold-rolled silicon steel and comprises a support. The broken belt cooling device is characterized in that a water tank is arranged on the support, two rolls are disposed in the water tank in parallel, and the heights of the two rolls are different. The broken belt cooling device for the continuous annealing furnace is simple in structure, small in size, convenient to process and low in cost, and is applicable to horizontal continuous annealing lines for silicon steel, tin-coated steel and carbon steel. In addition, the broken belt cooling device is convenient to install, use and maintain, and overhaul time for belt withdrawing operation after a belt in the furnace is broken is shortened.

Description

A broken belt cooling device for continuous annealing furnace

Technical field:

The utility model belongs to a broken strip water cooling device for a continuous annealing furnace, which is suitable for the production field of the continuous annealing furnace for silicon steel, and is mainly used for cooling the broken strip at the entrance of the continuous annealing furnace for cold-rolled silicon steel.

Background technique:

With the increase of market demand for cold-rolled silicon steel products, the production capacity of cold-rolled silicon steel has increased year by year, and the development of continuous annealing lines for silicon steel has become faster and faster. Due to the steel characteristics of silicon steel itself—high-grade silicon steel is brittle and easy to break, it is easy to break the strip during the high-speed annealing process. After the strip is broken, how to quickly deal with the broken strip and resume production has become a major problem for silicon steel manufacturers.

After the continuous annealing line of domestic silicon steel is broken, in order to cool the steel strip, water is often directly poured on the strip steel. The disadvantages are: ①The cooling effect is poor. ②wasting water. ③Wastewater flows to the bottom of the platform through the second-floor platform, polluting the clean production environment.

Invention content:

The purpose of the utility model is to provide a continuous annealing furnace broken belt cooling device which is simple in structure, clean, environment-friendly, energy-saving, can rapidly cool the broken belt of silicon steel, and is convenient for workers to draw the belt.

The utility model comprises a bracket, and is characterized in that a water tank is arranged on the bracket, and two rollers are arranged in parallel in the water tank, and the heights of the two rollers are different.

The usage method of the utility model is: after the strip is broken, the strip steel at the entrance of the annealing furnace has no tension, and the strip steel naturally falls in the water tank of the utility model. At this time, install two rolls (one is the sinking roll, i.e. the low roll, and the other is the steering roll, namely the high roll) in the water tank, the sinking roll is installed above the strip steel, and the steering roll is installed below the strip steel. Open the water inlet valve, and stop the water inlet when the liquid level is close to the water outlet.

Reverse the tension roller at the entrance of the annealing furnace, and pull out the steel strip in the furnace under the action of tension. The operator adjusts the opening of the water inlet valve and the water outlet valve according to the pumping speed to ensure that the cooling water temperature is ≤50°C.

The utility model has the advantages of simple structure, small shape, convenient processing and low cost, and is suitable for horizontal continuous annealing lines of silicon steel, tinned steel and carbon steel. The equipment is easy to install, use and maintain, and shortens the downtime of the belt-drawing operation after the belt is broken in the furnace.
