Abstract
The utility model relates to a water-cooled roller and bearing block assembly for a continuous casting machine and belongs to the technical field of metallurgical equipment. The water-cooled roller and bearing block assembly is characterized by comprising a roller (1) and a bearing block (4), wherein two ends of the roller (1) are arranged on the bearing block (4) through bearings; a blind hole (2) is formed inside the roller (1) along the axial direction; a steel tube (3) is arranged in the blind hole (2); the inside of the bearing block (4) is hollow; and a water inlet external screw (5) and a water outlet external screw (6) are welded on the bearing block (4) in a left-right symmetrical way. According to the water-cooled roller and bearing block assembly for the continuous casting machine, the temperature of a roller bearing can be reduced; the bearings are prevented from being clamped; a concave pit of an inner arc of a casting blank is prevented; and the quality of the casting blank is ensured.
Description
Technical field
The utility model relates to a kind of water-cooling type roller and bearing block assembly of conticaster, belongs to technical field of metallurgical equipment.
Background technology
As everyone knows; Two cold houses of conticaster, three cold house's temperature are very high; Work condition environment is abominable; The quality that is used to support the roller state of steel billet directly affects cc billet surface quality, and how to safeguard the duty that these are in the high-temperature area roller for a long time, then is the most critical issue that solves cc billet surface quality.Though roller in the past is lubricated good, does not consider temperatures involved, after bearing received scorching of high temperature, bearing can expand and be stuck in the bearing block, causes roller not change, and scratching appears in the strand outer arc.In addition, roller is when high temperature, and the iron scale that strand stays is very easy to be accumulated in roller surfaces, makes the strand outer arc produce pit, and slab quality has been caused influence.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and can reduce the roller bearing temperature, prevents that bearing is stuck, has avoided strand inner arc pit, has guaranteed the water-cooling type roller and the bearing block assembly of the conticaster of slab quality.
The purpose of the utility model is achieved in that
The water-cooling type roller and the bearing block assembly of the utility model conticaster; Comprise roller and bearing block; The two ends of said roller are installed on the bearing block through bearing, and the inside of said roller has blind hole vertically, are provided with steel pipe in the said blind hole; Said bearing block boring, left-right symmetric is welded with outer silk of water inlet and the outer silk of delivery port on the said bearing block.
Compared with prior art, the beneficial effect of the utility model is:
The water-cooling type roller and the bearing block assembly of this conticaster are offered blind hole in roller center, and in blind hole, place a steel pipe, let water flow to roller inside from the steel pipe the inside, come the pair of rollers cooling; And bearing block is also made hollow, and two outer silks of bearing block lower side welding are used to connect into, the metal hose of backwater; Roller and bearing have just obtained cooling like this, and bearing can expanded by heating and is stuck in the bearing block like this, and roller goes slick; Dead roller does not appear, and durable in use, and roller inside obtains cooling; Not yielding after being heated, the iron scale that roller surfaces is difficult to pile up strand makes the strand outer arc form pit, has guaranteed the quality of strand.
Description of drawings
Fig. 1 is the water-cooling type roller of the utility model conticaster and the structural representation of bearing block assembly.
Fig. 2 is the structural representation of Fig. 1 middle roller.
Fig. 3 is the structural representation of Fig. 1 bottom bracket.
Wherein: roller 1, blind hole 2, steel pipe 3, bearing block 4, outer 5 of water inlet, the outer silk 6 of delivery port.
The specific embodiment
Referring to Fig. 1 to Fig. 3; The utility model relates to a kind of water-cooling type roller and bearing block assembly of conticaster, comprises roller 1 and bearing block 4, and the two ends of said roller 1 are installed on the bearing block 4 through bearing; The inside of said roller 1 has blind hole 2 vertically; Be provided with steel pipe 3 in the said blind hole 2, said steel pipe 3 is used to feed the 1 cooling cooling of cooling water pair of rollers, said bearing block 4 borings; Left-right symmetric is welded with outer silk 5 of water inlet and the outer silk 6 of delivery port on the said bearing block 4, and silk 6 is used to be connected the metal hose of water inlet, backwater outside outer silk 5 of said water inlet and the delivery port.
Roller and bearing have just obtained cooling like this, and bearing can expanded by heating and is stuck in the bearing block like this, and roller goes slick; Dead roller does not appear; Durable in use, and roller inside obtain the cooling, not yielding after being heated; The iron scale that roller surfaces is difficult to pile up strand makes the strand outer arc form pit, has guaranteed the quality of strand.
Claims (1)
1. the water-cooling type roller and the bearing block assembly of a conticaster; It is characterized in that: it comprises roller (1) and bearing block (4); The two ends of said roller (1) are installed on the bearing block (4) through bearing, and the inside of said roller (1) has blind hole (2) vertically, are provided with steel pipe (3) in the said blind hole (2); Said bearing block (4) boring, said bearing block (4) go up left-right symmetric and are welded with outer silk of water inlet (5) and the outer silk of delivery port (6).
