## Abstract

Provided is a coolant spray module system for a heat treatment metal product, comprising: a first coolant spray module (1A), wherein the first coolant spray module (1A) comprises a first module housing (10), a first module cover (20), and a first nozzle (30), wherein the first nozzle (30) is fixed between the first module housing (10) and the first module cover (20) by first nozzle fixing blocks (13) and second nozzle fixing blocks (23), wherein the coolant spray module system sprays the coolant onto the heat treatment metal product to quench and clean the heat treatment metal product.

## Claims

### Claim 1

A coolant spray module system for a heat treatment metal product, comprising:
a first coolant spray module (1A),
wherein the first coolant spray module (1A) comprises a first module housing (10), a first module cover (20), and a first nozzle (30),
wherein the first module housing (10) comprises:
a first passing hole (11) provided in the first module housing (10), wherein the heat treatment metal product passes through the first passing hole (1);
a first coolant distribution pipe (12) provided on the first module housing (10) along an inner circumference of the first module housing (10); and
a coolant supply port (14) provided on an outer circumferential surface of the first module housing (10) and connected to the first coolant distribution pipe (12) via a coolant supply pipe (15),
wherein the first module cover (20) comprises:
a second passing hole (21) provided in the first module cover (20), wherein the heat treatment metal product passes through the second passing hole (21), wherein the first passing hole (11) of the first module housing (10) and the second passing hole (21) are aligned with each other along a first axis, wherein the heat treatment metal product passes through the first passing hole (11) and the second passing hole (21) along the first axis; and
a second coolant distribution pipe (22) provided on the first module cover (20) along an inner circumference of the first module cover (20),
wherein the first coolant distribution pipe (12) and the second coolant distribution pipe (22) are integrated together to form a combined coolant distribution pipe (12, 22), wherein the combined coolant distribution pipe (12, 22) carries a coolant,
wherein the first nozzle (30) comprises:
a first nozzle panel (32) in a disk shape;
a third passing hole formed in the first nozzle panel (32), wherein the heat treatment metal product passes through the third passing hole; and
nozzle grooves (31) provided on the nozzle panel (32) along an inner circumference of the nozzle panel (32),
wherein the first nozzle (30) is fixed between the first module housing (10) and the first module cover (20) by first nozzle fixing blocks (13) and second nozzle fixing blocks (23),
wherein the first nozzle fixing blocks (13) protrudes from the first coolant distribution pipe (12),
wherein the second nozzle fixing blocks (23) protrudes from the second coolant distribution pipe (22),
wherein the heat treatment metal product is in a round-bar shape or a pipe shape,
wherein the coolant spray module system sprays the coolant onto the heat treatment metal product to quench and clean the heat treatment metal product.

### Claim 2 (depends on 1)

The coolant spray system of claim 1, further comprising:
one or more additional coolant spray module, wherein the one or more additional coolant spray module includes a second coolant spray module (1B), wherein the second coolant spray module (1B) has substantially the same structure as the first coolant spray module (1A) and comprises a second module housing (10), a second module cover (20), and a second nozzle (30);
first and second module frame connection holes (16) formed at edges of the first and the second module housings (10) of the first and the second coolant spray modules (1A, 1B), respectively; and
a module frame (40) configured in a rod shape and inserted into the first and the second module frame connection holes (16),
wherein the first, the second, and the third passing holes are aligned with each other along the first axis.

### Claim 3 (depends on 2)

The coolant spray system of claim 2,
wherein the heat treatment metal product proceeds from an entry location to an exit location along the first axis to pass through the first and the second coolant spray modules (1A, 1B),
wherein the first coolant spray module (1A) is located at a first location between the entry location and the exit location,
wherein the second coolant spray module (1B) is located at a second location between the first coolant spray module (1A) and the exit location,
wherein the first nozzle panel (32) of the first nozzle (30), which is provided in the first coolant spray module (1A), is angled toward the exit location by a first angle with respect to a perpendicular plane, wherein the perpendicular plane is perpendicular to the first axis,
wherein the second nozzle (30) includes a second nozzle panel (32), wherein the second nozzle panel (32) has substantially the same structure as the first nozzle panel (32),

wherein the first angle is greater than the second angle.

### Claim 4 (depends on 2)

The coolant spray system of claim 2, wherein the module frame (40) comprises:
a module fixing block (41) provided between the first coolant spray module (1A) and the second coolant spray module (1B) and adjusting a distance between the first coolant spray module (1B) and the second coolant spray module (1B); and
a module fixing member (42) provided at an end of the module frame (40).

### Claim 5 (depends on 1)

The coolant spray system of claim 1,
wherein the combined coolant distribution pipe (12, 22) of the first coolant spray module (1A) is divided into two or more portions,
wherein the two or more portions include an upper pipe and a lower pipe,
wherein the first axis is located at a first level in height,
wherein the upper pipe is located at a second level higher than the first level, wherein the coolant is applied to the upper pipe at a first pressure,
wherein the lower pipe is located at a third level lower than the first level, wherein the coolant is applied to the lower pipe at a second pressure,
wherein the second pressure is maintained greater than the first pressure so that the coolant is sprayed out at a uniform pressure from the first nozzle (30) to the heat treatment metal product regardless of the location from which the coolant is sprayed out.
