Coolant spray module system for heat treated metal product

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.
