Abstract
The utility model belongs to the improvement of steel mill continuous casting crystallizer for plate billet steel leakage prediction system structure, particularly a kind of crystallizer bleedout prediction electric thermo system of improvement, comprise on crystallizer and hollow bolt seat is installed, coordinate in the endoporus of hollow bolt seat and hollow bolt is installed, thermocouple is inserted in hollow bolt inside, upper surface arranges annular groove to hollow bolt seat, coordinate in annular groove and O RunddichtringO is installed, the external diameter of annular groove is 54mm, internal diameter is 46.4mm, dark be 4.5mm, O RunddichtringO is the sealing ring be made up of polytetroxide ethene.The utility model structure is simple; can avoid causing in screwing operations sealing gasket squeeze rotten, leak; cannot copper plate temperature be detected after thermocouple can be avoided to contact water thus not have alarm function; hollow bolt can be reduced leak and cause thermocouple fault; a large amount of non-programmed halt can be avoided and block strand, guaranteeing administration measure direct motion.
Description
Technical field
The utility model belongs to the crystallizer bleedout prediction electric thermo system of the improvement of steel mill continuous casting crystallizer for plate billet steel leakage prediction system structure, particularly a kind of improvement.
Background technology
Current continuous casting crystallizer for plate billet installs crystallizer bleedout prediction electric thermo system online, and principle is that hollow bolt installed by crystallizer, and inner insertion thermocouple, is detected crystallizer copper plate temperature by thermocouple, changed judge casting blank shell situation by copper plate temperature.Hollow bolt end adopt sealing gasket seal, because sealing gasket material is excessively soft, cause in screwing operations sealing gasket squeeze rotten, leak; copper plate temperature cannot be detected after thermocouple contact water; do not have alarm function, cannot normally work, cause a large amount of non-programmed halt and block strand.
Utility model content
The purpose of this utility model is the crystallizer bleedout prediction electric thermo system providing a kind of improvement; its structure is simple; can avoid causing in screwing operations sealing gasket squeeze rotten, leak; cannot copper plate temperature be detected after thermocouple can be avoided to contact water thus not have alarm function; hollow bolt can be reduced leak and cause thermocouple fault; a large amount of non-programmed halt can be avoided and block strand, guaranteeing administration measure direct motion.
The purpose of this utility model is achieved in that a kind of crystallizer bleedout prediction electric thermo system of improvement, comprise on crystallizer and hollow bolt seat is installed, coordinate in the endoporus of hollow bolt seat and hollow bolt is installed, thermocouple is inserted in hollow bolt inside, and upper surface arranges annular groove to hollow bolt seat, coordinates and be installed with O RunddichtringO in annular groove, the external diameter of annular groove is 54mm, internal diameter is 46.4mm, be 4.5mm, O RunddichtringO is deeply the sealing ring be made up of polytetroxide ethene.
The utility model all can occur that hollow bolt leaks and causes thermocouple fault every day before the change of hollow bolt seal form, and breakout prediction cannot normally work.Cause a large amount of non-programmed halt and block strand, due to the uncertainty of accident, accident settlement causes a large amount of overtime works and assets expense expenditure.
The utility model change form of packers, sealing gasket is changed to polytetrafluoroethylene (PTFE) material sealing ring, its material is harder can not squeeze rotten in bolt screwing operations, and sealing effectiveness is better, efficiently solves crystallizer hollow bolt and to leak the situation that the breakout prediction that causes cannot normally work.
The utility model structure is simple; avoid to cause in screwing operations sealing gasket squeeze rotten, leak; cannot copper plate temperature be detected after avoiding thermocouple contact water thus not have alarm function; reduce further hollow bolt to leak and cause thermocouple fault; avoid a large amount of non-programmed halt and block strand, ensure that administration measure direct motion.
Accompanying drawing explanation
Be further described the utility model below in conjunction with accompanying drawing, Fig. 1 is perspective view of the present utility model.
Detailed description of the invention
A kind of crystallizer bleedout prediction electric thermo system of improvement, as shown in Figure 1, comprise on crystallizer and be installed with hollow bolt seat 1, coordinate and be installed with hollow bolt in the endoporus 2 of hollow bolt seat 1, thermocouple is inserted in hollow bolt inside, upper surface arranges annular groove to hollow bolt seat 1, coordinate in annular groove and be installed with O RunddichtringO 3, the external diameter of annular groove is 54mm, and internal diameter is 46.4mm, dark is the sealing ring that 4.5mm, O RunddichtringO 3 is made up of polytetroxide ethene.
Claims (1)
1. the crystallizer bleedout prediction electric thermo system improved, comprise on crystallizer and hollow bolt seat (1) is installed, coordinate in the endoporus (2) of hollow bolt seat (1) and hollow bolt is installed, thermocouple is inserted in hollow bolt inside, it is characterized in that: hollow bolt seat (1) upper surface arranges annular groove, coordinate in annular groove and O RunddichtringO (3) is installed, the external diameter of annular groove is 54mm, internal diameter is 46.4mm, dark be 4.5mm, O RunddichtringO (3) is the sealing ring be made up of polytetroxide ethene.
