Quenching Box

BSEW quenching boxes are designed and manufactured with high quality and suitable steels which have high resistance and strength against erosion and corrosion, according to international standards. Due to simple designstrong construction of quenching box is simple and safe. Quenching systems are used at hot rolling mill factories for rebar products to increase strength and hardness of production by applying pressurized water via special nozzles system.

Design of quenching system can be manufactured according to needs and type of hot rolling mill. The quenching boxes of length and number of ways (2 ways -3 ways ,4 ways) can be determined depending on the production line speed.

Roller Guide

Roller Guide for rolling mill are a series of rollers that determine the angle and direction of the steel as it is guided through the rolling mill to the mill roll. Since the friction on the milled steel is minimal, seizure is prevented and abrasion marks are reduced, making this machinery vital in improving the yield rate and quality of the product.

The general structure of these mechanical system may vary according to the characteristics of the material.

Types of Rolling Mill Guides

1. Static Guides
2. Converter Boxes
3. Double Roller Input Boxes
4. Four Roller Entry Guide Box

Y-Table

Y-Table is an automatic material handling system which ensures efficient handling of hot charge in a Rolling mill.

Roller Table Conveyor

In our industry, rolling mills are mechanical equipment used to achieve the metal rolling process, mainly consisting of rolls, roll bearings, rack, mill shoe, roll adjustment devices, upper roll balancing devices and roll changing devices.

BSEW has provided heavy duty Steel Mill Roller conveyors for steel mill applications, metal recyclers, and steel distribution facilities.

We have manufactured and installed specialty mill equipment for the following applications:

• Rolling mill loading and receiving
• Annealing line, chain and roller conveyor handling 20,000-pound steel plates loading and receiving from the furnace
• Batch pickling line with plate turn-up and turndown equipment
• Leveling, shearing, scrap, and transportation conveyors

Steel distribution facilities have many of the heavy loading requirements of the mill projects, but without the chemical, heat, or environmental impact that the mill projects require. Some of the equipment we provide to steel distribution facilities includes the following:

• Receiving conveyors from slitting and stacking equipment
• Tube pick and bundling equipment

Tube banding equipmentIn the rolling mill production unit, the roller table is important equipment for mechanization of production, especially in the production unit of section steel and bar, which runs through the entire production line. The roller table is the most common equipment for the rolling line of the entire rolling mill, and each section has a roller table. Due to the different positions of the roller tables, the role played by them is also different.The characteristics of the rolling mill production require that the roller bearing housing must be inspected frequently for frequent refuelling, while the traditional bearing housing upper cover is bolted. To check or refuel, the bearing housing upper cover must be opened, and the continuity of the rolling mill production does not allow frequent shutdowns, so the bearings are often short of oil and will accelerate bearing damage.

The conveyor roller is the largest number of equipment on the rolling mill production line and the faultiest equipment. Due to the continuity of the rolling mill production, the failure of any one of the roller conveyors on the rolling mill production line will cause the production to be interrupted. The bevel gear transmission roller supported by the traditional bearing seat is a commonly used structure in the production line of medium-sized and above rolling mills. However, the rolling loss caused by the rolling mill is very alarming. There is no shifting mechanism in the roller table, and the transmission is composed of universal joint shafts and variable frequency motors, and some are unpowered roller rollers. The roller table is variable diameter, such as the turning roller at the inlet and outlet of the rolling mill.

In the development of current rolling mills, it is developing towards continuous, automation, specialization, high product quality and low consumption, and in the future development, our rolling mill equipment will also be technically improved, and the application field will continue to increase.

 

Pinch Rolls

Pinch roll device is used to help the wire head rolled out by the finishing mill to enter the laying head to form a loop and to prevent the high-speed running wire tail from coming out of the rolling mill to accelerate the stacking steel due to the disengagement.

Pinch roll is the horizontal cantilever structure. It has a double roll device and one air cylinder which is used to control roll up and down synchronous clamp. Pinch roll is arranged before the entrance of wire discharger, respectively according to to the technical requirement of wire rod head, tail or full clamp clamping workpiece and turn it into the wire discharge machine.

The Function of Pinch Roll 

The pinch roll is placed at the entrance of the coiler. Its main functions are:

• Introduce the strip head into the coil guide inlet guide
• When the strip steel tail is thrown out from the wire rod block mill, the required tension is applied to the strip to obtain a good take-up shape
• A good roll shape is obtained by adjusting the level of the pinch rolls.

Parameters 

• Feeding specification: 5.5 ~ 16mm
• Feeding rate: 25~75m/s
• Pinch roll specification: φ183 × 72mm
• Max gripping force: 350N
• Maximum line velocity: 90m/s
• Speed increasing ratio: 6.92
• Electro motor model: DC Z4-180-41(DC Z4-180-41)
• Motor power: 55kW
• Motor speed:1500/3000 r/min

Twin Channel

 

Twin Channel carries the bar in a closed channel, minimizing the accident hazards.

• The basic and primary use of twin channel is to collect the TMT bars leaving the quenching boxes after being sheared by the flying shear in two strands
• The twin channel is capable of guiding the discharge of the rods from dividing shear.
• The twin channel is capable of collecting bars with size up to 40mm in diameter and have a maximum speed of about 25 meters per second.
• The closed twin channels ensure that the bars do not come out and maintain safely of the people involved in the process. The opening and closing of the channel are done through cam-shaft and follower rollers.
• The twin channels consist of alternatively opening flaps through a hydraulic cylinder and CAM system.
• The bar enters the closed flap that opens when the full bar has been obtained. It has a free fall on the straightening pockets of the rake type cooling bed, which moves on the fixed and moving rakes to the mill run out table.
