Abstract

Provided is a progressive straightening and stretching machine with five rollers and two frames, which spreads the straightening process of the casting blank in a longer section of straightening zone to reduce the straightening strain valve of the casting blank, thereby the quality of the casting blank can be greatly raised and the pulling rate of the casting blank can be increased. Besides, the stretching machine is capable of shortening the length of a rigid dummy bar and decreasing the storage height of the dummy bar, which is in particular adaptable for reconstructing a continuous casting machine of an old workshop with low rails. Simultaneously, the investment of the newly built continuous casting machine is reduced to some degrees.

Description

Dual 5-roller frames progressive straightening straightening machine

Technical field

The utility model relates to a kind of metallurgical cast steel machinery, refers in particular to the little square billet straightening machine in the continuous casting machinery.

Background technology

Existing billet caster, normally used is the straightening machine of single-point aligning, owing to locate to be easy to generate very big strain at single-point aligning point of contact, makes strand liquid core generation aligning crackle and presses the bundle crackle, influences the quality of strand; If such strand steel is melted production once more, not only wasted energy but also increased the production cost of enterprise.

Summary of the invention

The purpose of this utility model provides a kind of dual 5-roller frames progressive straightening straightening machine, and big in order to solve strand liquid core of the prior art strain, billet quality is poor, wastes energy, problem such as production cost height.

The purpose of this utility model is achieved in that the utility model mainly is made up of frame, pressed compact cylinder and throwing roller etc.; Its mid frame is separately positioned on the front end and the rear end of support, the upper and lower throwing roller of frame is located at the starting point of steel billet aligning, anterior frame and support tilt to set firmly, middle carrying roller is located on the steel billet aligning terminating point, the rear portion frame is parallel to support and sets firmly, the last throwing roller of two frames is directly driven by orthogonal axle sleeve vertical type speed reducer (change gear) respectively, is connected with in the lower end of the pressed compact jar support of rear portion frame and takes off the ingot cylinder, takes off the ingot cylinder and is fixed on the support.

Compared with prior art, the utility model has following effect:

1. strand liquid core strain value diminishes, and billet quality is good, improves the strand yield rate;

2. satisfy the needs of conticaster high-speed continuous casting, save the energy, reduce production costs.

Description of drawings

Fig. 1 is the structural representation of the utility model dual 5-roller frames progressive straightening straightening machine.

The specific embodiment

See also Fig. 1, front portion at aligning straightening machine support 1 sets firmly a frame, it is by upper spider 21, lower bearing bracket 22 constitutes, rear portion at support 1 sets firmly a frame equally, it is by upper spider 31, lower bearing bracket 32 constitutes, on upper spider 21, be installed with throwing roller 5, throwing roller 5 is one and drives orthogonal axle sleeve vertical type speed reducer (change gear) 51 by variable-frequency motor and drive, end at upper spider 21 is installed with pressed compact cylinder 8, one section of the pressed compact jar support 81 of its pressed compact cylinder 8 is affixed with lower bearing bracket 22, throwing roller 6 is fixedly arranged on the lower bearing bracket 22, and is vertical with throwing roller 5 center lines, and anterior frame and support 1 tilt an angle and set firmly.Establish a carrying roller 9 at the front end of rear portion frame, it is the terminating point of steel billet aligning section, and secured in parallel is identical with anterior rack construction in the rear portion of support 1 frame, and difference is the fixing position of pressed compact jar support 71 and rear portion frame, connect one and take off ingot cylinder 36, take off ingot cylinder 36 and be fixed on the support 1.

In sum, the inventor has reached the inventor's goal of the invention by the as above improvement of technical pattern.This structure can make the aligning of strand be distributed in one section long aligning district, the strand liquid core strain value of high pulling rate is diminished, the demand that is fit to current high efficiency continuous casting machine, overcome the strain that the single-point aligning produces, avoid the aligning crackle and the pressure of the liquid core generation of strand to prick crackle, improved the strand yield rate.
