Disclosed is a substrate polishing method comprising placing a substrate into a substrate polishing apparatus, rotating each of the substrate and a polishing pad of the substrate polishing apparatus, allowing a bottom surface of the substrate to contact a top surface of the polishing pad, and determining whether the polishing pad would benefit from maintenance. The polishing pad includes a plurality of annular regions that are homocentric with a central point of the top surface of the polishing pad. The step of determining whether the polishing pad would benefit from maintenance includes ascertaining a state of the bottom surface of the substrate, and selecting one of the plurality of annular regions by using information about the state of the bottom surface of the substrate. The one of the plurality of annular regions would benefit from maintenance.

The detacher includes a detachment body and a rotary part coupled to the detachment body, the rotary part includes a key protruding outward from the rotary part in a first horizontal direction, and the rotary part is configured to rotate about a central axis extending in the first horizontal direction.

Conditioning disk replacement apparatus and method

A method of batch-casting high-fluidity high performance concrete and low-fluidity high performance concrete, wherein the method is capable of batch-casting high-fluidity high performance concrete for forming a girder portion of a bridge and low-fluidity high performance concrete for forming a deck plate portion of the bridge by using a concrete casting apparatus. Accordingly, the construction cost can be reduced and the construction period can be shortened. In addition, because a cold joint does not occur, durability can be improved, and thus the life of the bridge can be increased.

A high-frequency heating method for a hot stamping process includes: a first heating step of high-frequency heating a steel sheet, which has an aluminum (Al) coating layer formed on an iron (Fe)-based base material, to a first target temperature at a first heating rate; a second heating step of melting the coating layer by high-frequency heating the steel sheet, which has passed through the first heating step, to a second target temperature at a second heating rate, wherein the second heating rate is lower than the first heating rate; and a third heating step of high-frequency heating the steel sheet, which has passed through the second heating step, to a third target temperature at a third heating rate, wherein the third heating rate is lower than the second heating rate. A compound is formed by a reaction between a material of the coating layer and a material of the base material in the second heating step. Therefore, the coating layer is not shifted even when high-frequency heating is performed at a temperature equal to or higher than the melting point of the coating layer.

Induction heating method for hot stamping process

A cooling apparatus for a hot stamping die is configured such that a refrigerant in a two-phase coexisting state of a liquid phase and a gas phase is supplied to a cooling channel formed in the hot stamping die to cool the hot stamping die using latent heat of the refrigerant. The refrigerant maintains a constant temperature in the cooling channel of the hot stamping die, which ensures uniform cooling of the hot stamping die.
