A quenching car comprises an open-topped body arranged to carry a load to be quenched. At least a part of the body is composed of walls of hollow construction to receive a liquid cooling medium, such as water. The hollow walls comprise inner and outer plate-like layers separated by reinforcing members which lie internally of the hollow walls, whereby the exposed surfaces of the inner and outer layers are substantially smooth and self-draining. The body is supported by girders of box-section extending along the length of the car. |
