Patent number: 9073119Abstract: A receptacle for handling molten metal is provided. The receptacle has bottom and side walls and includes a refractory defining a cavity within which the molten metal is conveyed or contained. The receptacle has at least one channel extending within at least one of its walls. The channel has an inlet and an outlet. The inlet is connectable to a source for circulating a fluid within the channel. The outlet allows the fluid to be expelled from said channel. The channel allows, when the fluid is circulated in it, to regulate the temperature of the refractory and thereby of the metal conveyed or contained. A casting assembly and a method for casting the refractory are also provided.Type: GrantFiled: June 7, 2013Date of Patent: July 7, 2015Assignee: Pyrotek Inc.Inventors: Sylvain Tremblay, Jens Bouchard, Michael Bouchard

Publication number: 20080156907Abstract: A mobile trailer for spreading a granular material mixture is disclosed. This trailer comprises at least two containers or bin compartments for containing a respective granular material, a movement-imparting assembly for moving the granular materials and a material mixer and spreader assembly for mixing and spreading the granular materials. Each bin compartment comprises a respective material-exit opening and the material mixer and spreader assembly is positioned near these openings. The movement-imparting assembly comprises a respective movement-imparting device mounted to each bin compartment for moving a respective granular material though a respective opening towards the material mixer and spreader assembly. A controller is linked to the movement-imparting assembly so as to selectively and independently modulate the speed of each movement-imparting device thereby modulating the ratio of each granular material received, mixed and spread by the material mixer and spreader assembly.Type: ApplicationFiled: January 2, 2007Publication date: July 3, 2008Inventors: Michel TREMBLAY, Marc-Andre LECLERC, Sylvain TREMBLAY

Publication number: 20050116398Abstract: Disclosed is a free flowing dry back-up material which comprises: from 67 to 96% by weight of fly-ash; from 2 to 15% by weight of a heat sensitive binder such as boric acid; from 2 to 7% by weight of a non-wetting agent such as calcium fluoride; from 0 to 10% by weight of a heat expandable material, viz. a material expandable as a function of the temperature such as vermiculite or graphite; and from 0 to 1% by weight of a dust suppressant such as kerosene. This material which is useful in particular in the aluminum industry has the advantages of being water free and free flowing, such avoiding the use of vibrator to position it into a shell. It also has a low density and a low thermal conductivity. Moreover, it is organic free as compared to the existing materials which use an organic binder to ensure a low temperature set; and it sets at a temperature lower than 400° F.Type: ApplicationFiled: November 28, 2003Publication date: June 2, 2005Inventor: Sylvain Tremblay
