Abstract

The utility model relates to a Y-shaped longitudinal water beam. The Y-shaped longitudinal water beam is composed of a longitudinal water pipe 1, a sliding block 3 and a Y-shaped branch 7 and is characterized in that the longitudinal water pipe 1 is supported and fixed on a cross beam 2, the longitudinal water pipe 1 is divided into the Y-shaped branch 7 at a uniformly-heating section 6, and the sliding block 3 is fixedly arranged on the longitudinal water pipe 1. The longitudinal water beam provided by the utility model is formed by mounting the sliding block on the longitudinal water pipe, and the longitudinal water beam is divided into the Y-shaped branch 7 at the preheating section. The Y-shaped longitudinal water beam provided by the utility model has the advantages that the structure is simple, a black mark on a billet can be eliminated and the product quality is effectively improved.

Description

The water beam indulged in the bifurcation font

Technical field

This practicality relates to a kind of device in a kind of steel heater for rolling steel, specifically is the improvement of a kind of vertical water beam in a kind of process furnace.

Background technology

Process furnace is the main Thermal Equipment of iron and steel enterprise, and wherein pusher-type furnace is one of main type of furnace of steel billet heating production, has characteristics such as simple in structure, easy to operate, that construction costs is low.The pusher-type furnace production technique is simple relatively, steel billet is delivered to into the furnace roller road by rollgang, the spring stop alignment, pusher transporting steel billet in the stove, the slide block of blank on the vertical water beam of upright supports moves, steel billet is heated to the steel rolling temperature in the stove in the process of operation, and the tapping steel billet is delivered to milling train through roller-way.

In order to guarantee stove inner column and vertical water beam and horizontal water beam (three is made into by thick walled steel tube) intensity at high temperature, adopt the vaporization cooling usually, water coolant will be taken away 15% heat; Slide block on the vertical water beam is passed to vertical water pipe by heat conduction with a part of heat, pass to ducted steam water interface then, cause the temperature of slider top to be lower than steel billet and go into 300 ℃-400 ℃ of stove surface temperatures, blank and slide block contact position form the black seal of bigger heating at preheating section and heating zone, and it is long that the black seal time is heated in elimination during to soaking zone, and furnace output reduces, and the blank that accounts for blank 90% surface-area is in the condition of high temperature, as overstand, oxidation is serious, and financial loss is big.And the black seal of bigger heating will cause that heating quality is poor, product mechanical property and surface size precision are low.Therefore from all many-sides, the influence of the black seal of heating is bigger, should alleviate as far as possible or eliminate the black seal of heating.

At present, existing and once had about eliminating the new technology that the black seal problem of heating adopts, all did a lot of effectively effort, as adopt the full hot-slide of porous to replace traditional type half hot-slide, be of great value invention, it efficiently solves the problem of the black seal of heating, but still has some deficits, the slide block material is had relatively high expectations, and invests bigger.

Summary of the invention

The purpose of utility model patent of the present invention is, need not increase under the prerequisite of more investment, effectively solves the problem of the black seal of heating, improves heating quality.

The utility model will address the above problem the technical scheme that adopts and be achieved in that by taking to change the arrangement form of pipeline, namely change the local bending degree of pipeline at the soaking zone discharge zone, a straight tube is changed into two bend pipes that become the bifurcation font to arrange, the contact position of steel billet and slide block is transplanted on crooked position and displacement by the starting position of shove charge like this, after the conversion of steel billet contact position, by heating and the soaking of soaking zone, the black seal basically eliminate at steel billet contact slipper position.

Inventive point of the present utility model is that it props up 7 by vertical water pipe 1, slide block 3, bifurcation and constitute, and it is characterized in that vertical water pipe 1 fixes on crossbeam 2, and vertical water pipe 1 is branched off into bifurcation at soaking zone 6 and props up 7, and slide block 3 dresses are solid on vertical water pipe 1.

Vertical water beam described in the utility model refers to install at vertical water pipe that slide block forms, and will indulge the water beam at preheating section and be divided into bifurcation and prop up 7.

The advantage of the invention is simple in structure, can eliminate the black seal of steel billet, effectively improves the quality of products.

Description of drawings

Fig. 1 is the vertical water girder construction synoptic diagram of bifurcation font;

Fig. 2 is the vertical water girder construction synoptic diagram of tradition;

Among the figure: 1-vertical water pipe, 2-crossbeam, 3-slide block, 4-preheating section, 5-heating zone, 6-soaking zone, 7-bifurcation prop up.

Embodiment

Below in conjunction with accompanying drawing, the mode that the utility model patent is solved the technical scheme that the technical problem of the black seal of heating takes is further described:

The vertical water beam of tradition is linearly to arrange in process furnace, steel billet is from going into stove to coming out of the stove, the a few lines in blank bottom contact with slide block all the time, the head temperature of slide block is lower than into the surface temperature of stove steel billet about 300～400 ℃, steel billet forms the black seal of heating via cryogenic slide when water pipe conducts heat cooling, it is big that steel billet (in earlier stage) in pre-, heating zone heat-processed forms the black seal of heating, and soaking zone (later stage) is eliminated the black seal of heating needs the time long.

The vertical water beam of bifurcation font is by changing water-cooled beam arrangement at soaking zone, be about to a linear pipeline and change into two pipelines that become the bifurcation font to arrange, make the initial point of contact of steel billet and slide block obtain changing, heating and soaking by follow-up soaking zone, improve the temperature in original black seal district, reached the blank temperature difference requirement of coming out of the stove.

After vertical water beam arrangement changes, blank will produce the thrust of a side direction to slide block when operation, in order to guarantee the stability of the vertical water girder construction of bifurcation font, increase fixed block on the slide block both sides, and fixed block is welded on the vertical water beam.

The vertical water beam successful Application of this bifurcation font is in the transformation of certain process furnace, and after the transformation, the temperature difference of the black seal of the blank heating of coming out of the stove is from before 55 ℃, be reduced to 15 ℃, improve heating quality, satisfied the requirement of quality product, also improved stability and the work-ing life of rolling equipment.

Claims

1. the water beam indulged in a bifurcation font, it props up (7) by vertical water pipe (1), slide block (3), bifurcation and constitutes, it is characterized in that vertical water pipe (1) fixes on crossbeam (2), vertical water pipe (1) is branched off into bifurcation at soaking zone (6) and props up (7), and slide block (3) dress is solid on vertical water pipe (1).
