2. Description of the Related Art In the above example, the block mill line has various equipments such as a rolling mill, a water cooling zone, and a cutting machine, and a guide for guiding rolled steel material is provided at its entrance and exit. Heretofore, as the guide, one made of casting or the like, or a carbon or the like for imparting lubricity to the surface has been used (see Japanese Patent Publication No. 54-8185, "Guide for Rolling Mills").

[Problems to be Solved by the Invention] In conventional guides, high-temperature and high-speed steel materials come into contact with each other, resulting in severe wear and surface defects called "scratch flaws" on the surface of the rolled steel material when passing through the steel material. Easy to do. Further, since the guide of the casting, which is guided at a high speed is a steel material, seizure occurs, and the steel material is apt to be flawed. Further, if the surface accuracy of the guide is not good, defects can still occur. Therefore, as a countermeasure against this, the surface processing accuracy is increased by polishing the guide made of cast metal.
However, this surface processing is also difficult.

The present invention has been made in order to solve the above-mentioned various problems, and conventionally, in order to provide lubricity, a softer material such as carbon is used as the material of the transfer material. Although it was used, the present invention found that when a high-speed steel material comes into contact with ceramics, the steel material does not have a flaw, but rather the surface of the ceramic becomes a mirror surface, It is based on this. Therefore, it is an attempt to prevent the occurrence of scratches and the like by reversing the idea of the conventional one and using a material that is harder than the material of the transfer material and does not have improved surface processing accuracy. The main points are as follows. That is, a ceramic metal lined with a protective member, a metal cap provided on the material inlet side of the guide, and a guide clasp provided on the outlet side of the guide. It is a material transfer guide.

[Effect] The guide of the present invention is made of a ceramic material that is harder than the material of the transfer material, even if it is used without increasing the surface processing accuracy, or when it comes into contact with the steel material in a soft state at high temperature and high speed.
On the contrary, the surface of ceramics is mirrored and smoothed,
Scratches do not occur, and since it is different from the material of the transfer material, seizure does not occur. Therefore, the projection on the guide caused by the seizure causes the transfer material to pass through the scratches one after another. Also disappears. Further, since it is made of ceramics, it has abrasion resistance and does not cause uneven wear. Therefore, the surface of the transfer material will not be scratched due to uneven wear, and the guide can be replaced by a conventional casting guide. 1/10 of the case is sufficient. In addition, since the inlet is protected by the cap, the ceramic guide body will not be damaged by the impact of the transfer material entering the guide, and since the stopper is provided at the outlet, the transfer is prevented. It will not be pushed backwards due to running friction of the material. Further, even if it is made of ceramics, since it has a considerable thickness and a backing member is attached, it can sufficiently withstand use in a harsh production line. In addition, it can be easily replaced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side vertical cross-sectional view of a ceramic metallic material transfer guide used when guiding a hot-rolled wire rod rolled by a rolling mill to a water cooling zone. Figure 2
It is a front view of the exit part. Reference numeral 1 denotes a guide main body having a cylindrical shape made of cast metal for lining, which has a brim 6 which is in contact with an inlet wall surface of a water cooling zone (not shown) at the center in the front-rear direction. 2 is
An inner cylinder (wear-resistant sleeve) made of ceramics,
On the inlet side (right side in FIG. 1) of the transfer material, the inner diameter is larger toward the end, and from the middle to the outlet side, it has an inner hole of the same diameter and is integrally sintered. Reference numeral 3 denotes a guide clasp (stop plate) on the outlet side, which has a hole having a larger diameter than the inner hole of the ceramic inner cylinder 2. Reference numeral 4 denotes a casting die on the inlet side, which has a shape similar to the inlet side diameter and the taper of the inner cylinder 2 as described above. Reference numeral 5 is a bolt for fixing the stopper 3 and the cap 4 to the guide body 1. First, in the guide body 1,
The ceramic inner cylinder 2 is inserted, the mouthpiece 4 is fixed to the inlet side with bolts 5, and the stopper 3 is also fixed to the outlet side with bolts 5. In this way, the integrated guide is inserted into the inlet portion of a water-cooling zone (room) (not shown) from the inside of the water-cooling chamber toward the outside, from the inlet-side mouthpiece 4, and the positioning collar 6 is inserted. It is stopped at a place and fixed in the water cooling chamber by the bolt 7 of the guide body 1. In the guide thus mounted, a steel wire rod rolled and stretched at high temperature and high speed by a block mill (not shown) is brought into contact with and guided by the casting die 4 on the inlet side of the guide. While being in contact with the inner surface of the inner hole at a high speed, it penetrates and is sent into a water cooling zone (not shown) in the next step. When the high-temperature, high-speed rolled steel material comes into contact with the inner hole surface of the ceramic inner cylinder 2 at high speed, the inner hole surface of the ceramic inner cylinder 2 becomes a mirror surface, smoothes, and scratches may occur. No seizure occurs. In addition, if the ceramic inner cylinder 2 is not pushed backward, even if the wire rod comes into contact with the guide inlet side base 4 portion, since it is not a ceramic portion, the inner cylinder 2 will be impacted by the impact. It will not be damaged. Further, even if the inner cylinder 2 becomes hot and vibrates, since it is lined by the cast guide body 1, it is not damaged. For replacement, the bolt 5 is removed, the inner cylinder 2, the inlet side cap 4 and the outlet side clasp 3 are removed and replaced with a new one. Therefore, replacement is extremely easy.
