Abstract
The utility model discloses a continuous casting machine fan-shaped segment frame cooling water system which comprises a water supply pipeline. The water supply pipeline is connected with a roll system bearing seat of a fan-shaped segment frame through a cooling water pipe, wherein the cooling water pipe is a three-way cooling water pipe. One end of the three-way cooling water pipe is communicated and connected with the roll system bearing seat of the fan-shaped segment frame, the other end of the three-way cooling water pipe is closely connected with the water supply pipeline, and a bypass cooling water pipe guides out the fan-shaped segment frame to communicate and connect with the water supply pipeline. Through the bypass cooling water pipe guided out from the inside of the fan-shaped segment frame, other parts of the fan-shaped segment are not affected. At the same time, the problem that corrosion resulted in water leakage of the cooling water pipeline of the fan-shaped segment frame is solved, offline frequency of the fan-shaped segment is reduced, online operation frequency of the fan-shaped segment is increased, quality of casting is improved, steel pass amount of a roll system is increased, and service life of the fan-shaped segment frame is greatly prolonged.
Description
Technical field
The utility model relates to a kind of continuous casting machine fan-shaped segment frames cooling water system.
Background technology
Fan-shaped section is one of core of continuous casting installation for casting, and molten steel namely enters the cooling and straightening of fan-shaped section continuation after forming the base shell by crystallizer.In work, fan-shaped section roll is direct supporting hot base, needs a large amount of machine cold water to carry out cooling, and these machine cold water are transported to respectively each roller by the sector-segment frames cooling water channel and are.On the one hand, because the material of sector-segment frames cooling water channel is generally straight carbon steel, cause sector-segment frames cooling water channel seriously corroded after using some cycles, drainage takes place frequently, particularly cooling water channel is positioned at sector-segment frames, and water route repair welding and to change difficulty larger makes the fan-shaped section maintenance of frequently rolling off the production line, and affects carrying out smoothly of steel mill's production; On the other hand, cooling water channel leaks, and directly to affect roller be required cooling water inflow, when cooling water inflow deficiency in roller system or when not having, roller system bearing temperature rises rapidly, the bearing locking, roller system stops operating, and causes that the wearing and tearing of roller system, roller are that spindle nose is broken, surface defect of bloom (as scratching) etc. series of problems; Again on the one hand, controlling rate of water make-up is an important indicator of continuous casting line production management, and cooling water channel leaks can increase rate of water make-up greatly, and normal production management is had a negative impact; Again, leaking of cooling water channel can flow directly on strand, can make the strand part cooling rapidly when leaking when more serious, leaking, and may cause strand to produce the quality problems such as chink, limit are split, internal structural flaw, may cause sleeping base when serious.
Summary of the invention
In view of above-mentioned present situation, the purpose of this utility model is to provide a kind of continuous casting machine fan-shaped segment frames cooling water system, has on the basis of former sector-segment frames structure, by framework bypass cooling water system, replace original cooling water channel, be convenient to welding and change when fan-shaped section is overhauled.
For achieving the above object, technical solution of the present utility model is: a kind of continuous casting machine fan-shaped segment frames cooling water system, comprise water supply line, and this water supply line is connected with the roller system bearing of sector-segment frames by cooling water pipe; The cooling water pipe that is connected between the roller system bearing of wherein said water supply line and sector-segment frames is a threeway cooling water pipe, this threeway cooling water pipe one end is connected with the roller system bearing conducting of sector-segment frames, the other end is connected with the water supply line sealing, and the bypass cooling water pipe is drawn sector-segment frames and is connected with the water supply line conducting.Therefore, the bypass cooling water pipe of drawing is positioned at the sector-segment frames outside, is more prone to when the water route repair welding with when changing, and can not affect the normal production of steel mill.
During this was novel, the exit of related bypass cooling water pipe had one section bending section to be connected with water supply line, and this bending section is the reducer pipe greater than the straight length that is connected.Therefore can guarantee water flow pressure and discharge by reducer pipe.
In above-mentioned, the threeway cooling water pipe is the stainless steel body.Can improve service life, avoid sector-segment frames cooling water channel corrosion seepy question.
In a word, the utility model has utilized the bypass cooling water channel of drawing in sector-segment frames, can other positions of fan-shaped section not exerted an influence, and operation and maintenance does not all change.Simultaneously, also solve sector-segment frames cooling water channel corrosion seepy question, reduced the frequency that fan-shaped section rolls off the production line, not only improved the quality of fan-shaped section online assignment rate and strand and the steel transportation amount that roller is, also greatly extended the service life of sector-segment frames.
Description of drawings
Fig. 1 is this novel schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Continuous casting machine fan-shaped segment frames cooling water system as shown in Figure 1 comprises water supply line 1, and the roller system bearing 3 of sector-segment frames.The present embodiment is to be connected a threeway cooling water pipe 2 between the roller system bearing 3 of described water supply line 1 and sector-segment frames, these threeway cooling water pipe 2 one ends are connected with roller system bearing 3 conductings of sector-segment frames, the other end is connected with water supply line 1 sealing, and the bypass cooling water pipe is drawn sector-segment frames and is connected with water supply line 1 conducting.The exit of the bypass cooling water pipe in the described threeway cooling water pipe 2 of the present embodiment has one section bending section to be connected with water supply line 1, and this bending section is the reducer pipe greater than the straight length that is connected.
In this was novel, threeway cooling water pipe 2 was to adopt the stainless steel body.Stainless steel 0Cr18Ni9.
The concrete installation:
1, with each hydraulic pressure, lubricated and cooling water pipeline complete removal on sector-segment frames, with burning torch, that original cooling water channel complete resection and cleaning polishing is clean;
2, processing technology hole on the roller system bearing 3 of sector-segment frames, fabrication hole needs and former water hole communicates;
3, according to the threeway cooling water pipe 2 of dimensional requirement welding sector-segment frames, after completing, the threeway cooling water channel welding of every group of sector-segment frames carries out separately the water pressure test, and pressure 12bar, pressurize 30min guarantee everywhere after ne-leakage standby;
4, with threeway but water pipe 2 be fixed to the correct position of sector-segment frames, firm welding;
5, weld each tube connector and various pipe fitting, the threeway cooling water pipe of sector-segment frames is connected with roller system bearing 3 and the exterior line of sector-segment frames respectively;
6, carry out at last Hydrostatic test, pressure 12bar, pressurize 30min guarantees ne-leakage everywhere.Whole cleaning is sprayed paint, and the threeway cooling water pipe transformation of sector-segment frames is complete.
