Abstract
The utility model discloses a steel billet ejection of compact roll table is with crashproof roller, including anticollision portion, anticollision portion right side extends transportation portion, and the bearing connecting portion is extended on transportation portion right side, and low in the middle of the high both ends of transportation portion, the biggest 20 ~ 30mm of diameter than minimum department, the biggest 40 ~ 50mm of anticollision portion diameter ratio transportation portion diameter, the biggest 140 ~ 150mm of bearing connecting portion diameter ratio transportation portion diameter, bearing connecting portion surface are provided with the bearing locating hole, and inside is equipped with bearing installation pore. This anticollision roller head is less than and closes on the steel billet for the roller can not wipe when rotatory and close on the steel billet, has solved because of the friction causes steel billet surface scab problem, avoids influencing steel billet surface quality, extension roller life simultaneously.
Description
Technical Field
The utility model relates to a roller, more specifically relates to a steel billet ejection of compact roll table is with crashproof roller.
Background
The steel billets are products obtained by casting molten steel smelted by a steel smelting furnace, and the steel billets can be mainly divided into two types from the manufacturing process: mould casting blank and continuous casting billet, the steel billet carries out the ejection of compact through the heating furnace, generally transport the ejection of compact roll table through the walking beam during the heating furnace ejection of compact on, the ejection of compact roll table comprises rotatory roller, the steel billet that the heating is good leaves the heating furnace through ejection of compact roller rotation, get into rolling process, because steel billet and steel billet interval are nearer in the heating furnace, when ejection of compact roller is rotatory, can rub next steel billet, cause the finished product to scab, influence steel billet surface quality.
Disclosure of Invention
Utility model purpose: the utility model aims at providing a do not rub and close on steel billet, avoid producing crashproof roller for steel billet ejection of compact roll table of influence to steel billet surface quality.
The technical scheme is as follows: anti-collision roller for steel billet ejection of compact roll table, including anticollision portion, the transportation portion is extended on anticollision portion right side, and bearing connecting portion is extended on transportation portion right side, and low in the middle of the high both ends of transportation portion, the biggest department of diameter is than the big 20 ~ 30mm of minimum department, and the biggest department of anticollision portion diameter ratio transportation portion diameter is little 40 ~ 50mm, the biggest little 140 ~ 150mm of bearing connecting portion diameter ratio transportation portion diameter, bearing connecting portion surface is provided with the bearing locating hole, inside is equipped with bearing installation pore.
Wherein, the tip of transportation portion is the circular arc that the radius is 20 ~ 25mm, the tip of anticollision portion is the circular arc that the radius is 5 ~ 8mm, the inside cavity of transportation portion for install the bearing, the inside 2 ~ 4 annular floor that are equipped with of transportation portion, annular floor centre bore diameter sets up with the bearing installation pore is concentric and the diameter is the same, annular floor is connected through the circular arc that the radius is 10 ~ 15mm with transportation portion inside, the inside anticollision portion pore that is provided with the bearing installation pore is concentric and the diameter is the same of anticollision portion, be used for firmly installing the bearing.
Has the advantages that: compared with the prior art, the utility model, its advantage is: 1. the head of the roller is lower than the adjacent steel billet, so that the roller cannot rub the adjacent steel billet when rotating, the problem of steel billet surface scab caused by friction is solved, and the influence on the steel billet surface quality is avoided; 2. the rollers do not rub the steel billet, so that the service life of the rollers can be prolonged.
